How the number of chromosomes and DNA in a male cell changes during spermatogenesis at the stages of: interphase I, telophase I, anaphase II, telophase II.
1) In interphase I, there are 2n4c or 46 two-chromatid chromosomes and 92 DNA molecules.
2) Telophase I – n2c or 23 two-chromatid chromosomes and 46 DNA molecules.
3) Anaphase II – 2n2c or 46 monochromatic chromosomes (23 at each pole) and 46 DNA molecules.
4) Telophase II – nc, or 23 monochromatic chromosomes and 23 DNA molecules in each gamete
