Vedclass · Answer

(B) The presence of $XX$ males or $XY$ females is a rare genetic condition often caused by the translocation of the $SRY$ gene (Sex-determining Region $Y$) from the $Y$ chromosome to the $X$ chromosome. During meiosis,an unequal crossing over event can lead to the $SRY$ gene being transferred to the $X$ chromosome. Consequently,an individual with an $XX$ genotype can develop as a male if the $X$ chromosome carries the $SRY$ gene,while an individual with an $XY$ genotype can develop as a female if the $Y$ chromosome lacks the $SRY$ gene.

Sometimes,the presence of $XX$ and $XY$ in males is due to:
