Hallo eveyrone

 

In male cells, the chromosomes x y are separated in anaphase

so how in the daughter cell there is the same genetic data as in the mother cell?

one cell got a x chromosome the the other y..

What did I miss?

No they do not, not in mitosis. The chromosomes are replicated before anaphase. Meiosis, on the other hand...

 

What did I miss?

 

A lot. Try looking up videos of the process of mitosis on youtube. There are plenty of them.

 

 

 

 

My very first post on these boards, so I figure I should start with a relatively easier topic

 

 

From what I can take away from your original post, it seems like you are getting Mitosis and Meiosis mixed up.

 

Mitosis is when each chromosome is replicated followed by cell division, so each daughter cell has one copy of each chromosome that originally came from the 'mother' cell.

 

Meiosis is when all the chromosomes pair up into 23 autosomal pairs and 1 sex chromosome pair. The pairs then separate during Anaphase and following cell division, form two haploid gametes. These gametes (from the mother) then fuse with gametes from another individual (from the father) to reform a diploid cell with the full complement of chromosomes.
