Yes, the speed, the voice level, the perfect diction, the pauses, and the well organized brain is a huge attraction and help in your biology lessons. Thank you very much, Craig.
Excellent video! Thank you so so much for this! Helped me so much! Wonderful presentation and explained in layman's terms so I could follow the whole video. Wow! Keep up the amazing work! Lots of Love and Gratitude comin' atcha! x
Around 10:42, when there is a non-disjunction in meiosis II, what causes the yellow sister chromatids to separate since they don't have the tension of the spindles pulling in opposite directions? thanks
This is a nice video. However, because of the common error of trying to use animals as a general example of eukaryotes, it includes an error that is maddening for those of us who study non-animal eukaryotes. Meiosis never makes gametes. Meiosis is a process of nuclear division, not cell division. Meiosis converts a diploid nucleus into haploid daughter nuclei. Gametes are cells, and cells that contain haploid nuclei can differentiate into gametes. Gamete nuclei may either be the products of mitosis (by far the most common case among eukaryotes) or they may be the products meiosis (a case limited mostly just to animals and ciliates). Also, many eukaryotes undergo somatogamy, so the gamete nuclei never occur in gametes, s.s. I realize that this is not something to swamp a beginner in biology with. However, meiosis should be described accurately with those features that are universal and related solely to nuclear processes. If you desire to use animals as an example, which is perfectly reasonable, describe the fates of the products of animalian meiosis with a brief prelude such as: " In animals, like us, the products of meiosis remain in cells that become..." It never hurts to be careful and precise, and it makes it easier for us who teach the biology of nonanimal eukaryotes to cover meiosis without having to unteach faulty, animal-biased paradigms.
Thank you XXYforLIFE. That is very interesting. I did not know that. So you are saying that while all Klinefelter's have 'XXY,' not all 'XXY's' develop Klinefelter's syndrome. Having an extra sex chromosome is is a genetic difference caused by non-disjunction. It is interesting because it shows us a flexibility in the human genetic system.

Mr Tyler best teacher ever!!❤❤

thanks to the producer. this video deserve praise
Awesome video. Very professional, pleasant and clear for understanding. Thank you!
i like your soft voice for teaching :) it makes it really easy to listen to lol most other videos feel like daggers in ur ears
Who else thinks Mr. Craig is a savage? Here from Mr. Tyler's class!
FRFRFR 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
i just luv ur soft voice
Great video! I really enjoyed your presentation. Thank you! ! !

thank you so much! your way of teaching very wonderful
SO HELPFUL. THANK YOU VERY MUCH
This was so helpful thank you so much
What about Trisomy 18? My daughter was born with this. Sadly, she died at 6 weeks old..
Voice is quite low
thanks for your videos

Thanks a ton!! Helps a lot

So this how Wolverine got claws....
what about trisomy 13 and 18? These exist??
Im pretty sure a trisomy can happen on any gene if the offspring survives though is another matter
Tres bien. I love how you say meiosis or should I say "meowmosis" :))
I love you
