Answer #1

The chromosome number in the somatic cells of Drosophila are 2n=8. The meiotic division is employed by eukaryotic organisms to produce sex cells( eggs and gametes). Meiosis is known as the reductional division as it produces cells with a haploid number of chromosomes or we can say it reduces 2n to n. Therefore, if the somatic cells contain 8 chromosomes, then the gametes which are produced by the process of meiosis will contain 4 chromosomes and ploidy will be haploid i.e n.
