Vedclass · Answer

(C) In $Drosophila$ (fruit fly),sex determination is based on the genic balance theory proposed by $C.B. Bridges$. According to this theory,the sex of the individual is determined by the ratio of the number of $X$ chromosomes $(X)$ to the number of sets of autosomes $(A)$. This ratio is denoted as $X/A$ ratio. If the $X/A$ ratio is $1.0$,the individual is a female. If the $X/A$ ratio is $0.5$,the individual is a male. If the ratio is between $0.5$ and $1.0$,it results in an intersex individual. Therefore,the correct answer is the ratio of the number of $X$ chromosomes to the number of sets of autosomes.
