Why are distinct chromosomes not visible within the cell dur

Why are distinct chromosomes not visible within the cell during interphase? At the end of which stage of meiosis does the cell transform from a diploid (2n: one pair of each chromosome) to a haploid (n: one of each chromosome only) state? What genetic recombination event of sexual reproduction takes place in meiosis but not mitosis? During which stage does it occur? Meiosis is the cell replication processes that must occur to form gametes. In spermatogenesis, however, mitosis also occurs so that males are producing sperm throughout their lifespan. During spermatogenesis, what cell is also performing mitosis? Identify the following stages of mitosis in the images below and place them in the correct order from first to last.

Solution

1. Distinct chromosomes are not visible during interphase because at that stage, each chromosome is thin elongated thread like structure. It is during the stage of propose that these chromosomes condense and become thick rod like structures and become visible.

2. After these stage of Anaphase I, Cell transforms from diploid to haploid because reduction of chromosomes occur during Anaphase I .
