(C) In $Drosophila$,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.Therefore,the sex is determined by the ratio of the number of $X$-chromosomes to the sets of autosomes.
