(C) The genic balance theory of sex determination in $Drosophila$ was proposed by $C.B. Bridges$ in $1921$.According to this theory,sex in $Drosophila$ is determined by the ratio of the number of $X$ chromosomes to the number of sets of autosomes $(A)$.If the ratio $(X/A)$ is $1.0$,the individual is a female.If the ratio $(X/A)$ is $0.5$,the individual is a male.If the ratio is between $0.5$ and $1.0$,it results in an intersex individual.
