Excellent 👌

[@MedicoVisual]

Thanks

[@abhinavrajiv986]

Excellently explained sir......thank you so much...... Sir but blood testes barrier not get cleared......as u said during crossing over.... certain changes occur to primary spermatocytes....which attracts immune cells....how it is possible..?? If so happens it happens it will become case of autoimmune disorder....!!! What types of changes occur during crossing over which leads primary spermatocytes to identify as foreign cells...???

Maza aya

[@Ersteller905]

hello sir you said from 46 chromosomes it will be 23 chromosomes* after meiosis but the 4 daughter cells that are formed after meiosis should have 23 chromatids* why we say that they have 23 chromosomes ? According to definition of chromosome it has 2 homologous chromatids?

[@MedicoVisual]

Even if a chromosome contain single copy (of chromatids) or double copies (double chromatids), it is still a chromosome, technically..

[@abhinavrajiv986]

Sir....when cytoplasmic barriers of spermatids broken..?? Are any factors help in breaking of these cytoplasmic barriers...???

[@houriak848]

Mitosis give 2 daughter cells different from parental cell ? Pls can u explain i think it's identical

[@MedicoVisual]

Yes, they are identical as far as the DNA is concerned. However they may become specialized into different type of cells. Please share the timestamp that you are referring to, so I know the context.

[@houriak848]

It's 12.10 u said that 2 daughter cells are different from parental cell but I think mitosis gives identical cells to the parent cell what makes them different if they go differentiation / How the spermatogonia gives one identical and one different that means that the other one has already gone for differentiation?

[@MedicoVisual]

@@houriak848 Yes, you are 100% correct. I made a mistake there. Thanks for pointing out

Hello aren’t you the guy attending Dr.Najeebs lectures preparing for USMLE?
