A) maleness
B) femaleness
C) infertility
D) None of the above
Correct Answer: D
Solution :
In Drosophila, the ratio of X-chromosome and number of complete sets of autosome determine the sex. Y-chromosome does not play any role in sex-determination. Presence of one or 2 X-chromosomes is more important than the presence or absence of Y-chromosome, eg, if X/A ratio is more than one the individuals will be superfemale. If X/A ratio is 1 ? Female. If X/A ratio is between 1-0.5 ? Intersex If X/A ratio is 0.5 ? Male and If it is less than 0.5 than super male.
