Vedclass · Answer

(C) In humans,males have one $X$ chromosome and one $Y$ chromosome $(XY)$,while females have two $X$ chromosomes $(XX)$.If a recessive gene is present on the non-homologous part of the $X$ chromosome,it will be expressed in males because they possess only one $X$ chromosome and lack a corresponding allele on the $Y$ chromosome to mask its effect.In contrast,females have two $X$ chromosomes; if they carry a recessive gene on one $X$ chromosome,the presence of a dominant allele on the other $X$ chromosome can suppress its expression,making them carriers rather than showing the trait.
