helpt alot thx vm

[al2275]

don't you HATE when the missus invades the man cave AND just hovers?!

[al2275]

ooh! What did you do?Looks like wifey came home & saw the mess you left from your pow-wow with the mates & you DIDN'T tidy up.

[al2275]

ooh! What did you do?Looks like wifey came home & saw the mess you left from your pow-wow with the mates & you DIDN'T tidy up. Don't you hate when they invade?

[Catalaayaa]

think i got it now though thanx!

[Catalaayaa]

why do all teachers tend to speak fast when they say something really important :(

[Catalaayaa]

so the sons only gets the allele from the mother?? dont get 3.23 :S

[TheMrMarMar13]

Thank you very much, you explained this better than my teacher

[magoshagolago]

Thanks! It was worth ten minutes to watch this...i didn't understand this up until now..

[pinoks1]

Sorry for what may be a stupid question, but at 4:05 you say that the woman has to be aa to not have the trait. She is not in the family, she is just married in, so why would she have the trait if she had f.ex Aa?

[bananasofcourse]

@pinoks1 She has to be aa to be recessive (Aa and AA is dominant). The reason she has to be recessive is because the circle is not shaded, which means she is not affected. Every time the circle or square is shaded, that means the person is affected. The reason recessive refers to being unaffected is because the screencaster, specifically at 4:00, was assuming the affected person is Dominant/Autosomal Dominant.

[AsianLlama]

Got so awkward when he noticed the other people in the room.

[CarterGuitar93]

Don't you hate it when someone interrupts your screencast... Thank you Douchy for your help and your podcasts throughout the year! Very much appreciated.

[eilan159]

Thanks!!! Great videooo

[charsiu12]

So, I would be marked wrong if i had said that it was autosomal, but unclear whether it was dominant or recessive?

[huntingbirdtv]

thank you for this explanation, but we don't have 10 minutes to spend on a single question in an exam situation.

[andrewdouch]

@huntingbirdtv That's true of course. But I doubt you would need to take anything like 10 minutes. It takes much longer to explain a technique than it does to use it. With a bit of practice, you should be able to follow the process in about two minutes.

[MatazLMB]

Well done!

[sumeet14226]

Absolutely love your videos, they are helping me out a lot... Thanks!!

[jgrove1224]

[joanolisa1]

OMG! You are intelligent! Thanks you thank you!

[minlibnein]

Thank you!

[serine456]

your awesome at explaining this



[pchenester]

please be my genetics prof please :) and thank you so much!

[arsenal1416]

you are the boss man

[karina31695]

i wish you were my biology teacher. you are so easy to understand and thanks for your help. i was so confused with this but now i understand it better.

[animerockz10]

omg i hav my genetics test tom n ure helpin lik crazyyy ahh why rnt there professors like u

[1223Melo]

Yet again, you are awesome dude.

[anthony9809]

very nice....well done. god bless you!

[RiotNoobs]

My Biology teacher is such a hack... Thus explaining why I am scouring the internet for what I'm supposed to be learning in school :) Thank you very much for an awesome explanation!

[Ametrida]

Really helpful!!! You explain this stuff really well. Thank you!

[gwjib04]

this is a great video, just as good as the 1st and good ending. this method is no too fast but thoroughness is more important

i like the kid lurking in the back too hahah

[mexicubanguy]

Thanks man you have saved my life

[flamex999]

GR 12 BIO EXAM HERE I COME!!

[Sluo1947]

OMG u are amazing!

[MagicEggPlum2]

Thanks Mr. Douch, it really helped me understand genetics on the pedigree. Hopefully  I do well in my genetics mid-term.

[MagicEggPlum2]

Thanks Mr. Douche, you really helped me understand about the pedigree. Im need this to pass my mid-term in three days.

[moldraxian]

Thank you Mr. Douch. Im in Biology Honors and this was killing me.

[lgadzik]

you should write a bio text book

[vinhkhanh2009]

Thank you for your help

[THE88DREAMERR]

But a recessive trait cannot goes down all over the pedigree! Am i wrong ??

[zackboomer]

got a 75 on my genetics midterm

[MEDddie]

That's Great!!!! I love it! Que bien, que bien!

[lizsayshello]

Awesome, this really cleared things up for me!

[QUESTIONERBR]

great stuff....

but plz, plz can you uplad tutorials for the more complex, extensive pedigrees.... (atleast one plz..... i know you are busy...:) )...

because i have gone on well, on the nuclear pedigrees... but i find it bit confusing when it comes to larger ones, with more than one likely modes of inheritances...

have a good day.....

[Arcane588]

I wish you were my lecture professor in my genetics class. My professor can't make the course interesting at all.

Great video :). Thanks a bunch!

[andrewdouch]

Ricebabi3 - not skipping a generation doesn't necessarily prove that a trait is dominant, (unlike skipping a generation - which does prove it to be recessive). But not skipping a generation does suggest that it's statistically likely to be dominant.

[ricebabi3]

excellent job! although to be clear this is autosomal dominant because it doesn't skip a generation =)

[LETTIS79]

You are a genius! thank you so much!!!

[robo2000nitro]

lmao at the kid hes like "dad wtf are you doing?"

[myphonei]

You are the best Biology teacher i know, naturally gifted, you make my lectures seem so dull. Thanks, you are a genious.

[lllexxx]

first: thank you! you are saving my exams!

second: i love the way you say little a :).

[icecream2b]

thank you =]

[watcinmetodi]

ah u talk too fast, i dont have time to think about it myself

[adidastenis4life]

dude...you're the man

[Jozyrose]

thank you, i actually understand it now=)

[itsMichellebitch]

Very helpful videos!

[aint1love4grand3]

You rock!

[crapi4got]

i wish you were my biology teacher

[valsera246]

@crapi4got That is exactly what I was thinking.

[fudge817]

@crapi4got Ikr! My biology teacher just gave us a few worksheets and barely explained this.Now we have a quiz on it and im not even close to ready with these pedigrees.He explained it so much clearer

[ruvvg]

brilliant stuff...gives me some clarity on this annoying subject

[Ametrida]

@ruvvg Indeed he brings clarity, but this subject is FAR from being annoying.

[brittaneynoela]

you are helping me revise so much! it's so beneficial to have someone talk me through all of this =)

thankyou
