Introduction to Heredity

[WhichDoctor1]

That dominance thing is definitely the case with chickens. We had two black chickens a few years ago, they both had one chick from a very colorful golden brown cockerel and they both produced completely black chicks.

[LeandraRose1776]

I love the little brown eyed baby! it's so cute!  ;)

[TheGreatBrendon]

was it awkward discussing your parents reproducing when making this video?

[TheGreatBrendon]

Sal...if i ever meet you in real life. i will give you the biggest hug ever and all the money in my wallet

[georgiaemily7]

THANK YOU SOOOOOOOOOOOOOOOO MUCH !!!!!!

[TheTdwpforever]

7:04 hahaha dominance, dominance, dominance.

[tutut37]

i love you. you saved me from a very nice failure in a higher level ib biology class

[TheTdwpforever]

what a sexy brown eyed girl.

comments like this is why i do so bad in school.

[MegaK311]

to: timetoflyyy--attending class is over-rated, lol. great video, no doubt!

[swat420]

the girl with the brown eye

[harrycool69]

I have blue eyes but I also have a "brown eye". How is that so?

[MrsJonas2038]

@harrycool69 this is just a simplification... in actuality there are many factors that influence eye color including shade, brightness, blending of colors, etc. :) Your DNA must contain genes that code for you to have this

[TheTdwpforever]

@harrycool69 cause you're dumbbbb

[thegetstoked]

you are my favourite person

[TheKidega]

This is day one of "studying"

...my test is tomrrow.

[313optical]

@TheKidega how much did u score kidega.....:D in the test

[Radiohead420DJ]

@TheKidega idiot... 

[herur47]

omg Sal, you are amazing :) but 'brown eyes' doesn't have an apostrophe in 'eyes'......

[scoringmachine1222]

Fuckin legend

[trumpet44girl]

My Geometry teacher knows this guy!

[irishactingboy]

Dominance...dominance.........­..dominance.

[timetoflyyy]

I've learnt more in 17 minutes, than in the 2 months of a genetics course in school.

[xXWhiteTiger21Xx]

what about hazel and dark brown eyes? would that be heterozygous?

[giriisindahouse]

I don't want to judge people. But isn't it sad that blonde hair, red hair, blue eyes, green eyes and straight hair are recessive?

[armyofchrist100]

Your eyes saw my substance , being yet unformed . And in your Book they all were written , the days fashioned for me , when as yet there were none of them ( psalm 139:16 )

[nirajrm]

Just for the information that the eye color is determined by multiple genes. Khan had used this as an example of trait governed by single gene to make it simple for understanding.

[thejesusfreak13]

It's funny because both of my parents eyes are very blue, but both of my siblings eyes use to be hazel and my eyes are gray . Then my brothers eyes turned blue and my sisters turned green. My eyes have stayed gray so far.

[giriisindahouse]

@thejesusfreak13 turned blue and green? Btw I'm Indian, dark hair and dark eyes so this is new to me. I heard about some people (heterozygous?) who suddenly have blonde hair growing. Is that also possible?

[thejesusfreak13]

@giriisindahouse Yes, it is very possible. I had a friend once that had red hair till she was eight or nine, but it turned blond. It's weird how the body works. XD

[xXWhiteTiger21Xx]

@thejesusfreak13 same with me, only I had blond hair when i was born, and it turned dark when I grew up. do you know what that's called?

[MrHartmanScience]

What program is this done on? Or does anyone else know of something similar? I would love to to this for my students.

[RAmiller666]

me eyes are very blue. girlfiend brown our children blue

[giriisindahouse]

@RAmiller666 either her mom or dad has blue eyes.

[oONeFerTitYOo]

Helped me alot! Thx!

[kotofu]

these drawings are much better than before. Upgraded to a pad?

[TheDarkDimensions]

I have blue eyes.. my gf has brown.. she's dominant :(

[giriisindahouse]

@TheDarkDimensions see if she's heterozygous by looking at her mom and dad. In that case, and if both your mom and dad are blue eyed then there's a theoretical 75% that your kids will have blue eyes.

[TheDarkDimensions]

@giriisindahouse Her parents both have brown eyes too. My dad has brown eyes and my mum has hazel :/

[twinkeltoes2009]

im recently studying genetics at school and the teacher wan'st the best at explaining but this helped me so much, thx a lot :)

[phantmenace]

Thanks, I really understand that now. Your'e the best!

[benakitodits]

He was gonna say a "Brown hot girl" :D lol

[PuRPLeTuTa]

I didnt want the video to end.. :(

[NitroNein]

this is like 8th grade material made understandable for 3rd grade

[rachelrod6]

You are a legend!! I've been watching all you're videos and I believe thats the only reason I understand Biology/chemistry/organic chem.

Thank you so much, please keep up you're good work!!! :D

[hasnat805]

hello, salman bhai ,u can make lecture for edexcel alevel biology.the lecture on dna was outstnding

[619daphne]

[FuzzBallFrost]

Whew thank god, my bio teacher sucks. And we have our o levels this year!

[FuzzBallFrost]

Whew thN

[reNastic]

Grazie for this! My professor is a douche bag who is fresh out of Grad School so we're just his lab rats & he has absolutely no idea how to convey these lessons properly.

[augenbrauen]

thanks from germany!

[AshyGailLove]

Thank you so so so much for this video!! My teacher fails to teach us a lot of things....correctly. Lol! And it makes it so hard to understand!

[gibboner911]

7 people really hate science... well dont worry, 155 hate you too

[cmonbugmenot]

around 12:15, doesn't the Dad's genotype typically go at the Top of Punnett square and the Mom's genotype on the Left of the Punnett Square?

[Dragan572]

@cmonbugmenot Doesn't really matter. It would give the same ratios

[iiSusTaiN]

@cmonbugmenot yeah thats what i thought too. i think he may of made a mistake

[sy8095]

dude fuck you my teacher turned this video into a fucking homework assignment

[iheartladygaygay2034]
