Solving Genetics Problems

[@hap4832]

This is probably the best online tutorial I've watched. The voice is very clear. It was not so fast and not so slow. And Im actually learning. Thumbs up!

[@alleliascott8519]

Clear, concise, and a great place for my students to go and review when they get tangled up on their homework! I'll be using this for review before major exams and the End of Course test as well!

[@JaiMeyrick1]

Really like the vid! Got an exam coming up with a genetics unit and this was really helpful :)

[@dashy_london3937]

I really like the way you explain! It is really clear and you show enthusiasm on the field. thx

[@joeyhurrle5471]

I have a dream that one day this nation will rise up and expel the horrid teachers that stalk this Earth, and replace them with the Penguin Prof I have a dream that one day on the red hills of Georgia, the jocks and nerds will be able to sit down together on the internet, and fully understand complex scientific concepts thanks to the Penguin Prof I would continue...but I got an exam in 2 days! (Thank you so much for explaining 54 pgs of biology in 13 minutes)

This video blew my mind by how well it is made. You have really great pedagogy. Plus your voice is nice to listen to :) Thank you!

[@Penguinprof]

Thanks so much!!!

[@Penguinprof]

The female you are talking about (X+Xc) is heterozygous and will be a carrier - and that's what makes X-linked traits different. If a male gets one copy (XcY) he will be color-blind; a female needs 2 copies (XcXc) to actually BE colorblind. Hope that helps!

[@korinamanese6042]

i have been studying this for 3 weeks and my prof only makes it complicated i am so glad i found this vid!

[@Penguinprof]

I'm so glad I could help!!

[@ahmedkotait]

Everything in this video was on my unit test! thank you every much!!!

[@paolaoriada4848]

Thank u so much for this.In my school teachers arent soo good.I had a dream to be a radiologist since a kid but the teachers make me loose my dream .Here i found again a hope to be what i want.Go on please and help us .Lots of love

[@vancarylbodiola9453]

Thank you so much! this tutorial definitely enlightened me about solving probabilities in Genetics.

[@naginakhan3621]

I am feeling so good, very well explained

[@ramchanderraoodela1928]

very good presentation with easy to understand the tough problems . happy to see at east now .i will pass on the message to known persons,.thanks

[@melissarainchild]

you explain things in a great way. nice and relaxed...I rewatched this one several times (and took not, of course) Thank you

[@mahnoorkhan8982]

One of the brilliant educational videos and channel i've come across on youtube!

[@Beatle214]

I LOVE YOU! Thank you!!!! I can't believe I didn't see this before!!!!

[@phozisaphozie1772]

I did enjoy

[@hamilton5465]

You're such a good teacher. Thanks this helped me a lot. Great job!

[@brittanycallen7974]

I wish all videos on youtube had this nice of a voice.

[@kwnazli]

I realllyyy love you. I had an exam on thursday and im confused but your video is solved my problems thanks

[@Penguinprof]

This makes my penguin heart so happy! 🐧🐧

[@ravitejaraviredmills]

awesome professor!.. your explanation just brushed by basics.

[@gwynethisman4620]

so is this conditional or unconditional probability?

[@bhartiparihar]

This was wonderful!! Your explanation is very well done! Thanks!

[@isabelprz2674]

this was an amazing explanation thank you.

[@NautrallBeauty]

you're an excellent communicator. Thanks!!

[@Penguinprof]

+NautrallBeauty Thank you so much for watching!

[@DannysFearless]

Thank you! Please make more Genetics Videos!

[@KMMK2371]

Awesome explanation! Thank you so much!!!

[@Penguinprof]

You are SO welcome!

[@luxlux1607]

Thank you, this is an awesome video! Helped me out heaps :)

[@Penguinprof]

+lux lux So glad to hear it!

[@kritikakoul85]

thanks a lot for this lesson Totally changed my world of genetics:-)

[@kb9658]

This was very helpful, thank you for the clear explanations!

[@ivh007]

You mean 2 dominant alleles @ 9:46. I know it doesnt make a difference to the end result. But it confused me for a bit.

[@NayeonKim]

THANK YOU SO SO SO MUCH! :D

[@Penguinprof]

+twentysevenwanders You are so welcome!!!! :)

[@ingothitrust5248]

Why does the probability scheme fall apart when you have 2 Heterozygous parents to find the probability of Heterzygous offspring? Obviously through the Punnett square, it's obviously 50% of 1/2 but when you use probability, it comes out to 1/4 or 25% Am I missing something here?????

[@Penguinprof]

Remember that Hh is equivalent to hH, so you need to add 1/4 + 1/4 to get 1/2.

[@psptubegray]

can you pls do this with out the square.... In horses, B=black coat, b=brown coat, T=trotter, and t=pacer. A black pacer mated to a brown trotter produces a black trotter offspring. Give all possible genotypes for this offspring.

[@PastorKemp]

So, if you have a homozygous dominant parent with AA and heterzygous dominant parent with Aa; What is probability of getting offspring of aa? Would it be 0?

[@Penguinprof]

Yes - it would be 0. There is no way to have an 'aa' offspring, since it would need one recessive allele from each parent and the AA parent does not have one to donate.

[@alliasokan8993]

need more to be explained.... nt a little bt need much!

[@ujalaabbas1861]

Thanks a lot..u hve cleared a very complex thing easily

[@DarkPrinceNH5570]

Yes I have a bump on the side of my left hand like its a birthmark. Its not, I use to have a 6th finger. Im polydactyly. Its rare to see I guess amongst people on earth. Yes others have it but the chances of getting its rare. I was inherited this through my blood.

[@Amitsuman101]

Very informative, clear n understandable. Thank u..

[@gypsypikis]

wow this was amazingly helpful!!

[@1farhinmomtazriana25]

Thanks a lot. It was really helpful.

[@jennyyedid2]

at 9:27, how come the answer is not 9/64? Since its 2 to the 6th power, shouldn't it be out of 64? (1/4 p x 3/4 Q x 3/4 R = 9/64 pQR)

[@Penguinprof]

It's 1/4 (pp) x 1/2 (Qq) x 1/2 (RR) = 1/16 Not sure where you're seeing 2e6... Remember, if each parent is Pp for example, then for the offspring to be pp, that's a prob. of 1/2 from EACH PARENT to get it's recessive allele, so 1/2 x 1/2 = 1/4. You may be over-thinking it - I'm not sure. I hope that helps!

[@01aarbear]

So helpful, thank you, you're awesome!

[@Penguinprof]

+Carolina Cobian Thank you!!! And thanks for watching. :)

[@sruthiize]

wow, what a good video, understood perfectly

[@psyren1723]

Helped a ton!!

[@hibahakim7890]

Thank you so much!

[@CaptainCalculus]

Hmm where I live there are signs warning that penguins cross at night, and the police will stop you if you are driving carelessly.

[@Penguinprof]

Australia or NZ??? GO LITTLE BLUE PENGUINS!!!

[@CaptainCalculus]

ThePenguinProf Eastbourne NZ

[@alokkumarverma1162]

Really appreciate it thanks and excited

[@sarashaikh1416]

wow this made a lot more sense!

[@DarkPrinceNH5570]

The 6th finger on my left hand was cut off at birth. Other famous people and ROYAL FAMILY MEMBERS are polydactyly too. Look it up.

[@istel3283]

great video for genetics.....

[@Jjhperlas]

love it!! thanks for doing this video

[@bettyromandia6567]

*Can anyone recommend research paper writing service?*

[@jeanahukle4148]

*essay.4v20.all-about.in* Finance paper was a total disaster for me before I found this website. I didn't know where to start, what to write, but they showed me everything and now I am sure that with their help I can cope with any possible assignment.

[@ravitejaraviredmills]

is this still in need?

[@somethingsafoot]

write ur own essays idiot

[@jeanclaude6284]

Uzaam Syed lolz!!! Super Savage

[@tigerhawk9712]

How is 1/6+1/6= 1/3???

[@MM-gl7ll]

1/6 + 1/6 = 2/6 = 1/3

[@G5Nvm]

boy wtf

[@kirstenyu9258]

thank you!! super helpful

[@DarkPrinceNH5570]

So if Im polydactyly does that mean I could have more or less chromosomes? If anything with the chromosomes it should mean I have more chromosomes. I bet I dont, I bet its normal. It could be something else that caused that deformity at birth. I dont want to say anything just yet because I dont know enough about biology but yeah I been to hell and back. Its messed up and I was always curious about this.

[@thesilkyone2]

Awesome. Thank you

[@snehadas5627]

Thanks a lot.. helped me a great deal :) :D Keep going ! :)

[@Penguinprof]

+Sneha Das You are so welcome! I plan to!!! :)

[@anam3575]

I like your videos... thank you

[@ameen6796]

Maths is great !

[@liganjinxeseverything3174]

My word... genetics is not so very different from linear algebra and matrices. Anyway, pretty good presentation.

[@acsejapan]

Thank you!

[@margaritacalderon1475]

so helpful! thank you :)

[@margaritacalderon1475]

I have a biology test talking about only the punnet squares this video made it really easy to understand.

[@jonathanramirez4830]

Thanks!! I like penguins too!

[@AndreaGracie]

Fantastic. Thank you!!!

[@loujainmhanna8404]

So helpful thanks

[@Penguinprof]

Glad it was helpful!

[@axe4770]

I LOVE YOUUUU

[@mistymcclure1955]

Can A+ mother and O + father. Can they make an AB+ baby

[@Penguinprof]

Nope. That B antigen has to come from someone!!

[@marissah1413]

Very helpful!

[@edgargonzalez2768]

Thank you!!!

[@MsPilpilon]

Great video very useful Tnx!

[@Vickyvictoria90]

Great vid!!!

[@kislikalkulator]

11:18 i need this part for presentation. (Shortcut)

[@cd3dnw]

Thanks!

[@reneric1]

why isnt the probability of having a color blind child (in your example) 1 in 4? there are two squares with Xc

[@bhagya2624]

this really helped me, thank you

[@Penguinprof]

You are most welcome!!!

[@essamalyk9218]

Thank you ♥️

[@Penguinprof]

You are most welcomle!

[@PoisonousPotato69]

God damn this is easy after this video

[@makeupartistinbangaloredee6349]

Good video

[@Penguinprof]

Thanks!!

[@peterojugo7542]

you rock

[@DarkPrinceNH5570]

I dont know enough about biology but it hasnt been proven no matter what. This is weird because they put stuff in media saying this all the time as if I reminded them of someone in the past recorded in a history book or journal that no one knew about. So who did I turn out like?

[@divyanarayan3723]

Thank u

[@bonnielee7559]

I did NOT get this

[@learnnetneetintamillanguag5049]

super thanku

[@okaypinkplays9893]

@5:47 i see what you did there

[@Penguinprof]

+rose'n'games That was the required intersection for my dating criteria - Fabio was the result. :)

[@truax1101023]

That albino kid will haunt my dreams

[@TheArgarc]

Females have to carry two copies of the color-blind allele to be color blind. Males only need and can only accept one sex linked allele for the phenotypic trait to show.

[@rahulsonaniya7636]

if son have blood group A and AB and daughter have blood group A and B find the blood group of parents

[@recentnews7151]

Nice

[@RebelLife05]

12:53, why is the mother not X+ X+..since she is carrying the color blindness, 13:19, why is the male child chosen as the answer,

[@dustinwebber8904]

the mother is stated as a carrier, this means that she has that recessive trait but doesn't express it...therefore it is correct the way it was shown

[@mailynruth5704]

The comments are all years ago, y'all still alive out there?...

[@Penguinprof]

Yup, still here!!!

[@spiderman_2579]

Thanks mam

[@Penguinprof]

You are welcome!

[@mhdsbz807]

ausome....

[@okaypinkplays9893]

@1:40 dat face tho...

[@okaypinkplays9893]

penguin.....? O_o

[@yogeshgupta4667]

a colour blind man marries a woman with normal sight who has no history of colour blindness in her family. What is the probability of their grandson being colour blind??

[@belieberbeth123]

autsomeee👏🏽😂

[@TheFutureGhostHunter]

more lke your showing off what you know verses teaching... sorry but it is good ideas and share... but teach more

[@ben456tone]

Why are you talking about mathematics instead of genetics that too in a sloppy way

[@PinkiSingh-tb8mo]

nic1!

[@okaypinkplays9893]

+Pinki Singh ikr???

[@PinkiSingh-tb8mo]

+rose'n'games what??

[@okaypinkplays9893]

something

[@1028wash]

Thank you!
