Answer:
The Y chromosome do not go through crossover
Explanation:
Typically, genes from the mother and father are shuffled -- or, "cross over" -- to produce a genetic combination unique to each offspring. But the Y chromosome does not undergo crossing over, and, as a result, its genes tend to degenerate, while repetitive DNA sequences accumulate. Each chromosome is made up of DNA.
Answer:
In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.
