Vedclass · Answer

(B) In humans,the sex of a child is determined by the sex chromosomes inherited from the parents. Females have two $X$-chromosomes $(XX)$,and males have one $X$ and one $Y$-chromosome $(XY)$. $A$ father contributes either an $X$ or a $Y$-chromosome to the offspring. If the father passes an $X$-chromosome,the child will be a girl $(XX)$. If the father passes a $Y$-chromosome,the child will be a boy $(XY)$. Therefore,a child who inherits an $X$-chromosome from her father will be a girl,not a boy.

$A$ child who inherits an $X$-chromosome from her father will be a boy.
