Vedclass · Answer

(B) According to the genic balance theory proposed by $C$.$B$. Bridges in Drosophila,sex is determined by the ratio of the number of $X$ chromosomes to the number of sets of autosomes $(A)$.$1$. If the ratio $\frac{X}{A} = 1.0$,the individual is a normal female.$2$. If the ratio $\frac{X}{A} = 0.5$,the individual is a normal male.$3$. If the ratio $\frac{X}{A} > 1.0$ (e.g.,$1.5$),the individual is a superfemale (metafemale).$4$. If the ratio $\frac{X}{A} Therefore,a ratio of $1.5$ indicates a superfemale.

According to the genic balance theory of sex determination in Drosophila proposed by Bridges,which $\frac{X}{A}$ ratio indicates a superfemale?
