Detailed explanation-1: -In the case of the fruit fly, half of 8 is 4, so the haploid number is 4. Therefore, the gametes of the fruit fly would have 4 chromosomes.
Detailed explanation-2: -Drosophila melanogaster, the common fruit fly, has 4 chromosomes in each of its gametes.
Detailed explanation-3: -Every body cell of a fruit fly has 8 chromosomes. Every fruit fly gamete (sperm of egg) has 4 chromosomes.
Detailed explanation-4: -Final answer: The fruit fly has 8 chromosomes (2n) in each cell. During interphase of mitosis, if the number of chromosomes at G1 phase is 8, what would be the number of chromosomes after S phase is also 8.
Detailed explanation-5: -Eight chromosomes are found in the somatic cells in fruit flies, suggesting they have 2 pairs of four chromosomes. Mitosis ensures that each cell generated executes the correct functions since they are similar to the original cell.
