"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

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.

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).

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

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

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

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

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.

wonderful explanation but no gene mapping , bummer!

it so makes sense now, thank you!

That writing speed though!

Very good explanation! Thank you!

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

Well explained!

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.

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

that was really helpful thank you ❤️

Nice explanation, Thank you very much!

Great work

Really cleared that up thanks

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

it is really difficult to get, thanks.

very good explanation, thank you

So amaaaaaazing

Plz add extra nuclear radiation@Khan Academy

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

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 ?

Thank you!

Pls upload Chromosome walking elbortly....

Describe how restriction mapping is carried out

This is a great EDUCATIONAL VIDEO

Thanks

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

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?)

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.

Pls can I get mcq book or web site about genetics

Pls upload chromosome walking detail vedio

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

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

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

No gene mapping

Is purple pink or am i triping

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 ...

Well aren't you rude.

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

Is it just me or is she chewing gum ?

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

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!

not good...worst
