The somatic cells of the Drosophila fly contain 8 chromosomes. Determine the number of chromosomes and DNA molecules in cells during spermatogenesis in the reproduction zone and at the end of the gamete maturation zone. Justify the answer. What processes are taking place in these zones?
During smermatogenesis in the zone of reproduction or division, cell division occurs by mitosis, the number of chromosomes is 2n (8), and the number of DNA molecules is 2n (8).
At the end of the maturation zone, 4 haploid cells are formed, the number of chromosomes is n (4), and the number of DNA molecules is n (4).
