(B) The genic balance theory of sex determination was proposed by $C.B. Bridges$ in $1921$ based on his studies on $Drosophila$ $melanogaster$.According to this theory,sex 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 it is $0.5$,the individual is a male; and if it is between $0.5$ and $1.0$,the individual is an intersex.
