Genetic Mechanisms of Sex Determination | Learn Science at Scitable xxx drosophila


Although both mammals and fruit flies produce XX females and XY males, their chromosomes achieve these ends using very different means. In mammals, the Y chromosome plays a pivotal role in determining the male sex. In Drosophila, sex determination is achieved by a balance of female.

In Drosophila, the chromosomal basis of sex determination is due to the ratio of X chromosomes to sets of autosomes. Recall that, in Drosophila, n = 4: one sex.

Drosophila flies have both X and Y chromosomes, as well as Sex is instead determined by the ratio of X chromosomes to.
