This vid is very useful for me i love byjus coz it's explain very well with animations ❤ and tomorrow there is my science exam and i know nothing of this chapter before this video 🎥 thanks a lot to all byjus teachers 👩🏫
First you said male and female reproductive cells (gametes) have only 22 chromosomes only and then later in the video, in ovum topic you divide them into 22+x & 22+x. And in sperm topic you divided it into 22+x & 22+y. But tell me how did the each one get 44 chromosomes if each always have 22 only ??? Explain me
Maam:- Do we all have a satandard height? Is it fixed (wait for it) that the girls are "5 feet 5 inches and the boys are 6 inches tall" Me taking a solid 1 minute to under stand that ma'am meant 5 ft 6inches not just 6 inches,
I have a question that in that picture (where you just teach us about chromosomes) why there is two two chromosomes in one chromosome...i hope that you have understood my question
Pretty simple. She said we have 46 chromosomes in each cell. 46/2=23 Which means 23 pairs So in one pair we have two chromosomes! Hope that made it clear?
