A Beginner's Guide to Punnett Squares

Paul Andersen introduces the Punnett Square as a a powerful tool in genetic analysis. He tries to address major misconceptions that students have when use a Punnett Square. He gives a number of examples of monohybrid crosses and one example of a dihybrid cross. The square is a simple tool that uses the outcome of meiosis to determine possible offspring in a cross.

This was more helpful then what my teacher taught in the last 3 weeks.

[@melitonaltarejosiii9101]

+Victoria Jaimes Yeahh. . .. this was more helpful for me too .

[@gamingtec101]

+Victoria Jaimes my teacher made us watch a video that Even i could do better!!!

[@liganjinxeseverything3174]

I agree. I don't even study genetics yet and it makes sense 😆. Well, maybe my mathematics has something to do with it...

[@sovereignviper]

+Victoria Jaimes Exactly. This is the problem with the education system. I'm likely going to fail biology because to professors nowadays everything is a big joke. This video is amazingly clear and professional compared to what modern college professors are doing

My god, why can't all bio teachers put some emotion into their voices like this when they teach? Bozeman is the first one I've heard that doesn't sound like a monotone robot. Can't tell you how much I appreciate that Bozeman, thank you so much for this helpful video!

[@amyrose45876]

My teacher gives A LOT of emotion in his voice :P

[@Aliaisawesomeable]

Seriously? I'm so jealous. ;P

[@gamerroyal659]

Ana Lin totally agree with you my bio teacher sounds like a robot too only when she looks at you its like the terminator is there

[@Aliaisawesomeable]

That sounds quite terrifying, but at least there's something there to keep your mind awake & alert for.

You're the best teacher I've ever had.

[@marsplanet7702]

My teacher is a legend who actually explained it right and then gave us this vid if we had any troubles at home.

[@ajhowell7672]

You're the only reason I'm going to pass my test tomorrow. I wish you were my bio teacher. She goes so fast and yet takes a week to teach this, and you teach it in 12 minutes. Your the goat mr Bozeman plz keep doing this for as long as you live.

11:18 "It's super hard to do this on a test, you're rarely gonna have to draw a diagram." My professor: NO BACKUP WORK SHOWN NO POINTS

[@jenniferbostrom2679]

Day before test, this helped me so much because before I didn't understand the function of the Dihybrid cross but now I do! Thank you.

[@katerinakonstanstinova5272]

This has taught me more about genetic crosses then any of my biology classes ever have

[@fabizoe6342]

We have remedial modules due to COVIC-19 and this really helped because we hadn’t gone over this in class yet

[@thegmanofEAP]

Just wanted to throw a big thanks your way! My professor, bless her heart, jumps through and over complicated stuff like this, and you've really helped me to grasp this in a way that's not all that complicated.

[@Sandra-fj3ou]

It's so helpful. I watched 3 or 4 videos about Punnet Square before I watch this one, and I cannot really understand thing, it's so logic tho. Then I saw this one, and watched it. So helpful for someone that English is not your original language. Because the words is not really difficult to understand. Hope someone see this comment will has a great grade on both their test and homework. 🤗

[@mydology1089]

When no video is there to help. You're there. Unparallel videos. THANK YOU SO MUCH

[@jamesmyers2087]

I am an older student in an art major curriculum retaking biology because... not really sure. Maybe the school thought it might help me mix egg tempura colors. It's been a running firefight to maintain the grade average I need and more of a challenge than I thought I'd have. But I just want to say that quite a few of the cell division, reproduction and genetic topics were so much easier coming from your videos than the McGraw Hill textbook. You've got a real gift for instruction. Owe you big time and thanks.

[@MrWubbbWubbb]

I'm here because my teacher is a prick and won't explain how to do these!

What a useless teacher!! . He shouldn't even be teaching then !!

[@allzzjn]

I relate. She just showed us a picture of a punnett square, said, "This is how it's done," and made us answer a whole test right after. Also, she is not good at explaining. Not at all.

[@QueenBeeTV88]

He doesn't want you to learn so you won't take his job :D

[@rinnmb3640]

YOU ARE THE BEST TEACHER I'VE NEVER HAD! THANK YOUUU

[@TheSpartan425]

This guy is amazing. I always learn something when I watch his videos.

[@pranavsood2058]

KC .Palidan IKR he just made it 3000 times easier for me

[@haroldinho__9377]

great thats so awesome. How about you roll all those thoughts up and put them in the bin.

[@rchallender2493]

I'm so glad I got to have Mr. Anderson as my biology teacher in high school!! Best science teacher I've ever had! He always explains things in a way that just makes sense 👍🏻!!

[@curtpiazza1688]

Wow...it s been over 40 yrs since I had biology....but I think I m starting to get it!

[@Akosilors]

When my teacher asks me how I got this before we even started this lecture, I'm gonna say Mr. Andersen taught me. XD

[@genecooper5742]

sir, i owe you my life this semester

[@sapnaagarwal3054]

Thank you for your time today, Mr Anderson ☺☺☺

[@isaacsudduth1574]

I found this to be very insightful. I'm working on a sci-fi story and one aspect of the story is that some interstellar colonists, usually the first generation of settlers, that had to undergo genetic augmentation in order to properly adapt to the environment of the planet they intend to live on. I've mostly been using the mono cross to figure out the possibility of two augmented parent and the type of offspring they would have, but now I see its a little more complicated than that.

[@arxalier2956]

That's so cool, I hope your story does well

[@melissaperrin1554]

Mr. Anderson, Thank you for your clear lectures. I really have appreciated both your chemistry and biology video!

[@Aeroprodet]

Me: ok finally I am doing work My kindergarden-level brain: hahaha pp

[@johnnaranja7639]

fr

[@retired001]

For the dihybrid cross, in order to get your letters in position, think of FOIL (the way my teacher tought us) F: First O: Outter I: Inner L: Last (Ex for this vid) First "R", First "Y" Outter "R", Outter "y" Inner "r", inner "Y" Last "r", Last "y"

[@kitcooper2710]

Thank you. This guy helps sooo many people. I wonder how many people passed a test cause of him.

[@alexxasanchez5969]

Thank you so much! I had such a hard time trying to figure this out and you explained it perfectly! Your greatly appreciated :)

[@subashrigarimalla4032]

Thank you, Bozeman Science. This is of great help.

[@faraznahyan1768]

You sound exactly like Tina :D

[@Phoenix-np1iu]

this is the comprehensive review of a bunch of topics that i needed

[@japreet_kah]

Underrated video, explained to a mind that does not know anything, unlike teachers where they try to explain to someone as if they already know the answers and are stupid for not understanding

[@TheCraziwhitegirl]

Oh my gosh, thank you SO SO SO much for this video! My teacher is really lazy and just hands out worksheets and expects us to already know the information. I have a test tomorrow on this and you made it really simple for me. :)

[@mariavemo9838]

"THANK YOU" i know it sounds crazy but i didnt understand it until i saw your video thank you!!!!!!!!!!!!!!!!!!!!!!!!

[@giancarloespinoza2197]

Legit, the only reason I'm passing my AP Bio class is this channel. Thank you.

[@kristiepie74]

Last one: 1:1:1:1 : one round yellow, one wrinkled yellow, one round green, one wrinkled green! Nice! So helpful!

[@TheEstarENT]

Thanks bro good job , it helped a lot I have a test tomorrow and now I'm confident

[@marisamoore8875]

This helps so much! Thanks so much! Im in a college biology course and all your videos help me a lot!!

[@user-ow3po2jn6q]

You explain very clearly than other teachers Thankyou for explaining

[@jakepokemonman1227]

You basically just summed up a week of my class that now makes sense to me. Thanks, test tomorrow.

[@tenzzomkyi]

ohhh.. the last one is a 4X1 punnet square since rryy's only possible gamete is ry, and RrYy produces Ry, rY, Ry, AND ry

[@salami99]

Yes, and that means is a 1:1:1:1 ratio. That answer is accepted on the Free Response math.

[@ihaveanavocado7377]

i thought it was 4:8:4 lol

[@Kamoisabozz]

Why cant this guy teach my AP bio class, FML

[@sarahcalderon1902]

I love how in just over 12 minutes you explained this better than my current teacher! thank you!!!!

[@nataliarothwell8749]

I actually understand this topic now, thank you soooo much😅

OMG, thank you! I understand this way better than my PAID teacher could ever teach me in 10 minutes. Thank you!!!

[@sofiavaldez3020]

[@seokhwa.]

Thank you! Your are more helpful the my asshole teacher who said "I'll show you how to do it tomorrow" and he never did now I have a test next hour so I hope I pass 🤞

[@Ricketythetruck]

Thank you for your help. this was great in assisting my son in his genetics homework

[@fancydreaming]

This guy is amazing. I rarely understand anything in class, but I'll be sure to understand with Mr. Andersen.

[@harshwardhanpatil4849]

Sir, you taught it simple, easy and quick. Loved it. It was awesome!!

[@wolvina]

Wouldnt the square be 1X4 ? Since RrYy can produce 4 different letter pairs ( RY, Ry, rY,ry), and rryy make one possible pair ( ry) ? so would it be geno rate = 1:2:1 and pheno rate 1:2:1? I could be totally wrong....

[@aroweno7]

1:1:1:1 1 round and yellow, 1 round and green, 1 wrinkled and yellow, 1 wrinkled and green.. that's what i got

[@ksstuff315]

Thank you for saving my life!

[@ilovealfieboe11]

Thank you so much! Before I watched your video, I was so confused regarding dihybrid crosses and how to set them up, etc. Now, I am a lot more confident about them and for the first time am not dreading my biology test. You've earned yourself a new subscriber. I'll be sure to share this video... thanks again!

[@watermaster6]

Every time I'm studying for a test, this guy helps me understand so much. Great job with your videos! keep it up

[@User89018]

I am here because my college professor is terrible at explaining biology imagine paying tuition and have to use KZbin lol

[@angelambedzi1224]

Atleast i understand it better unlike the way my teacher was teaching i was so confused thankyou KZbin u made Genetics crossing easier for me

[@HoneysucklePoison]

Thank you thank you. Never learned this in high school (I home schooled myself lol) and now in college my professor breezed over it thinking we all knew it already. Life saver!!

[@RobinRobin-lt9mf]

i’ve been learning this in school for the past 2 months and couldn’t understand it and now i’ve clocked it in about 2 minutes

[@massakhwaja7306]

For me Mr Andersen's videos work much better than Khan academy videos. No disrespect to Sal, he is amazing for everything he has done it just doesn't process well with me. I have watched all the chemistry and biology in both playlists. This is more structured and easily digested then the Khan series. It is my secret weapon!
