Vedclass · Answer

(D) In humans,sex determination is primarily governed by the $XY$ system,where $XY$ individuals are typically male and $XX$ individuals are female.However,the $SRY$ gene (Sex-determining Region $Y$) located on the $Y$ chromosome is responsible for male development.If a translocation occurs where the $SRY$ gene segment is transferred from the $Y$ chromosome to the $X$ chromosome during meiosis,an $X$ chromosome carrying the $SRY$ gene can be inherited.Consequently,an $XX$ individual inheriting this $SRY$-carrying $X$ chromosome will develop as a male.Conversely,an $XY$ individual who loses the $SRY$ gene segment through translocation will develop as a female.Therefore,the correct answer is the translocation of a segment of $X$ and $Y$ chromosomes.

Sometimes $XX$ males and $XY$ females are produced due to:
