Seven years later and these videos are still helping college students. Kudos to you my man!
I'm studying B.Sc Honours degree in animal science.... After 6 year long break after completing my undergraduate degree. This video has helped me with my assignment in animal breeding and genetics at a postgraduate level. Hats off to you Sir and your team. Much love from South Africa.
I just want to give you a "Thank you very much". This is probably the best explanation about Meiosis that I have ever seen. Wish you the best
Best meiosis explaination I've ever gotten
The best explanation on Mitosis and Meiosis. I never really understood both until after watching this video. Big thanks to you Professor.
Thank you!! I love all your video's! definitely helps me better understand when you break it down by steps and have a visual that goes along with your explanation!
I needed this, now i finally get it. thank you
Your videos are truly the best and the most interesting, in understanding Mitosis, Meiosis, and so many other Biology concepts on You Tube! I love your teaching! Thank you for making these videos!
Your videos are so helpful! I wish you were my professor, you make everything so much easier to understand.

Great explanation ! The best, and I have watched many videos.
Thank you. Perfectly clear!
This is very helpful,it makes my lesson very easy and fascinating to my learners.
Finally understand this THANK YOU!!
GREAT TUTORIAL!! THANKS 🙏
Last month of my Bsc in medical science and finally, your presentation made meisosis click! thanks!
really grateful to watch ur video an simple but understandable video of meiosis big thanks!
I loved it! This is better than my teacher reading off the biology book. :)

I've been confused over this for more than a year...No teacher could explain it this clear. Thank you so much sir ,you saved me.
Thank you so much! This video is really helpful! I appreciate it if you please explain spermiogenesis.
Very helpful video Lots of love from India🇮🇳

Amazing it has helped me😊
Thank you so much 😊
thank you.
I know that my question doesn't really match with your presentation, but with your background, I have this question.since I have no way to get in touch through personal email, I am posting my question here. I am very pleased that you follow me. I have one of those questions, quite of no sense question! It could obvious for most of the scientific but not for since I don't any lab. Just wondering if it's possible to flip a cell to examine it or both sides are already tricky for me. A cell has tree dimensions, the layer of a cell - (liver for example - facing the outside from the layer facing the inside - toward sisters cells - are they the same. To put it another way. The cell layer facing the outside world, just like us facing the external world and the other side is facing the inner world. Both has to deal with a totally different environment. Are they still alike or not?
U r awsome...m lucky to find u
Excellent.
Good guy.... thumbs upppppp
Awesome. Thank you.

Thank you so much, very helpful and great for test reviews. Honestly I make great progress with your video reviews. Just a small note as a fan maybe try a new mic? Just because in earphones I get a loud whisper noise at the end but other than that great!

I liked the video and it was easy to inderstand meiosis I request you answer the questions asked at the end

This is an answer I received: "So, the short answer is no. In terms of peripheral membrane proteins glycoproteins, there are different signal transduction pathways going on in the two faces of bilipid membrane. Also, the lipid composition would be different as they have to deal with different environments. And then you have the primary cilium which extends up to 25uM outside and emanating from the centrioles/centrosomes. In terms of studying inside vs outside, this could be done in terms of permeabilization techniques. In IF microscopy, after fixation, you have the option to permeabilize whether or not you want to study internal or external proteins. Hope that helps!"
Thankyou very much
So helpful
Hello Beverly...I'm a little confused...if 2 haploid cells are already formed in Meiosis 1 y do we need to have Meiosis 2?
doesn't meiosis occur before the sperm and egg meet? If so then why do you have mom the chromosomes labeled as mom 1, dad 1, mom 2, etc.? otherwise video was extremely helpful and very clear!!

+astrocat Keep in mind that life is a cycle. Pretend a woman named Jessica has a mother named Susan and a father named Paul. Meiosis will create egg cells within Jessica's body. But remember that Jessica inherited her chromosomes from her parents Susan and Paul. Therefore, Jessica has maternal chromosomes (those inherited from Susan) and paternal chromosomes (those inherited from Paul). I hope that helps.
plz upload the vadio topic is: RNA transduction
So one pair=1 tetrad ?
Can you make this unique best type of videos for all chapters of biology of class 10 icse?
The video was very helpful...... I hope your subscribe rs increase more an more..

sir where is chiasmata?
@BeverlyBiology

+nazni nazni During crossing over, the chiasmata is simply the location where the two chromosomes physically connect to cross over.
In sperm cells do we have 23 chromosomes or 22 pair of autosomes and a x or y chromosome...???..

Some sperm cells have 22 single autosomes and a single X chromosome... some have 22 single autosomes and a single Y chromosome.

Clinical applications 🥴??
About your sense of humor in regard of the smile on the sperm design cells... they should have a terrified face knowing what they will have to go through in the journey to the reproductive female system... They all die in pain!
