What happens if the ratio of X chromosomes to autosomes in Drosophila is 1:1?
Option: 1
The individual develops as a male
Option: 2
The individual develops as a female
Option: 3
The individual develops as a hermaphrodite
Option: 4
The individual fails to develop
Answers (1)
The sex of a person is determined by the individual's X chromosome to autosome ratio in Drosophila. One X chromosome and two sets of autosomes, at a ratio of 1:1, produce a female fly. This is due to the fact that in Drosophila, the development of a female requires the presence of two X chromosomes, whereas the formation of a male requires the presence of one X chromosome and one Y chromosome.
Option 2 is the correct answer.
