Solution
In Drosophila, the male sex chromosomes are XY and the female sex chromosomes are XX.
Explanation:
The sex chromosomes in Drosophila are responsible for determining the sex of the fly. Females have two X chromosomes (XX), making them homogametic, while males have one X and one Y chromosome (XY), making them heterogametic. This chromosomal arrangement influences inheritance patterns, especially for sex-linked traits.
