"we count chromosomes by the amount of centromeres present" - finally somebody said it that clear; you could add to your def. that the equation counts for 1 centimorgen; btw i like your voice

[@centozo]

I've been studying this stuff for over a year now and it's not until now I've clarified this concept out. I don't know why that's so hard for some people.

[@UkbunemalYokanlush]

Does single chromatid contain centromere? If yes, then it is correct, otherwise, by that logic of counting centromeres, humans would have 23 chromosomes and not 46 (which is the case).

[@guychi-chifly950]

@@UkbunemalYokanlush what is your opinion on optical genome mapping?

[@melissarainchild]

Yay! I get it now! More distance = more probability! Thanks!!

[@MADDYXD124]

A good sensible reason will be more helpful 😒

[@KamuiAlmighty]

This is just another video on recombination. There is no gene mapping involved here.

[@Sammyyaam]

Exactly. Why are there so few gene mapping problem vids? It's so frustrating.

[@joeya5438]

Recombination is a method with witch you can map genes in a chromosome. What are you looking for? Sequencing the base pairs?

[@mpforeverunlimited]

Joey A yes, sequencing

[@strangeperson5670]

You comment saved my time thanx

[@TripleIProductions]

1:45 this has confused me for a long time, so I just memorized it before. It's great to have a simple answer like that.

[@sushmitasingh3326]

wonderful explanation but no gene mapping , bummer!

[@Joeythegoats]

Thank you so much! I was getting a same question wrong again and again! Your presentation helped me a lot to understand how to solve.

[@tchkbty7489]

Best video 😭😭😭😭😭. Thank u sooo much ma'am for explanation in such detail.

[@gappy10123]

This video FINALLY helped me understand this concept THANK YOU!!! lol

[@EternalFootman-kr6yx]

she is well versed in science fiction

[@simalot1]

That writing speed though!

[@somasafir1218]

that was really helpful thank you ❤️

[@alenah2382]

it so makes sense now, thank you!

[@farzadrahimi9005]

Nice explanation, Thank you very much!

[@bingereader12]

Can u pls do videos on deeper genetic engineering concepts? I really love ur videos...

[@bolin110]

Well explained!

[@李湛元]

Very good explanation! Thank you!

[@jessicaneamtu9053]

Thank you!

[@gg3675]

Really cleared that up thanks

[@abdullahshahnawaz6585]

Thanks

[@rezamahmud5416]

if the frequency of swapping over is 6% then what I don't understand is that why did it swap at all? Didn't she say that they are less likely to recombine if the distance is closer ?

[@onimichael178]

Describe how restriction mapping is carried out

[@revancedyoutube-zy1jt]

Maturity is when you realize that khan academy is not owned by khan sir

[@shahrierahmed410]

Plz add extra nuclear radiation@Khan Academy

[@AhmadJcho]

it is really difficult to get, thanks.

[@MohamedSalah-ki5ij]

So amaaaaaazing

[@malumaha5821]

Pls upload Chromosome walking elbortly....

[@SABIANS85]

Is Gene mapping and chromosome mapping is the same thing??

[@leavesofdistinction2252]

Yes and no. I'm a genealogist. I do family histories. So... To me, gene mapping is not the same. It's more of a relationship mapping and not necessarily as a recessive gene would be shown. i.e. mapping out classmates vs. mapping medical issues in a family

[@himu5425]

Pls can I get mcq book or web site about genetics

[@JosephineEbejerGrech]

very good explanation, thank you

[@nareshsapkota]

is it same process in autosomes as well as sex chromosomes?? will it be differnet in case of autososme?? please expain!

[@jamalelldenadam6055]

Great work

[@sriranjanisrinivasan4347]

Hey, then what is the extent of recombination of the blue and green genes? Is it more likelier than the recombination of purple and green?(cuz of greater distance?)

[@sriranjanisrinivasan4347]

I feel the concept of greater distance thus greater recombination is false. Lesser the distance greater the transformation is true

[@Alexa-pc6ux]

I know I'm late, but nope. The more the distance there is between them (Linkage distance), the more crossing over there is between them (Recombination), so in other words, a recombination with blue and green would be greater because of the great distance.

[@dma67111]

Anyone not affiliated with bio/science would think recombine is to put back together not separate. Lol

[@juneribaldi7093]

This is a great EDUCATIONAL VIDEO

[@qasimedustudio9392]

Best

[@malumaha5821]

Pls upload chromosome walking detail vedio

[@samferrer]

Thank you for this video ... but I think you wanted to mean ... 6% out of 100 meiosis events recombination will happen between the two given gens ... correct? It means that centimorgan is actually a unit of time ...

[@Potato-ic5hx]

I thought the same. But im not sure myself. Can you explain or confirm if possible? The comments is 6 years apart though... please let me know if you learnt further on this topic!

[@plantsscience7505]

No gene mapping

[@sonemanibitna3053]

If I only heard that digression in high school

[@madaraoma949]

Is purple pink or am i triping

[@YesYasmin]

Tripping

[@ritikachauhan1151]

Sorry to say....but impo. Also...Are you gone mad continuosly saying purple colour to magenta and pink

[@anshikakulshrestha1050]

RITIKA CHAUHAN why does it even matter?

[@ashdash3681]

Well aren't you rude.

[@monaiwahedi3445]

I´m sorry, but the video is talking about chromosomes and chromatids for 3 minutes until it gets to the point. Please get to the point, we wouldn´t be watching the video if we didn´t know what a chromsome and a chormatid is/ look up gene mapping to begin with!

[@gustavolsen4074]

Is it just me or is she chewing gum ?

[@AVMMM]

Talks too much.. Not on poin most of the time.

[@rukhsaryusuf4432]

this is crossing over not gene mapping. you wasted my time

[@arupswargiary5149]

not good...worst
