Answer:

O Fruit fly gametes have 2 chromosomes while parent cells have 4 chromosomes.

Explanation:

The fruit fly is a diploid (2n) species with a chromosome number equal to 4, which means that somatic cells have two sets of homologous chromosomes, each set composed of two chromosomes (2n = 4). Moreover, fly gametes are haploid (n) cells, containing each a complete set of two non-homologous chromosomes (i.e., half the amount of DNA compared to parent cells). During meiosis, a single cell divides twice following one complete round of DNA replication, producing thus four gametes with a haploid number of chromosomes.
