Vedclass · Answer

(B) Statement $(a)$ is correct: $X$-linked genes are typically found on the non-homologous region of the $X$-chromosome.Statement $(b)$ is correct: In $X$-linked recessive disorders,a female with one recessive allele on one $X$-chromosome and a dominant allele on the other is a carrier.Statement $(c)$ is incorrect: $A$ carrier female is usually asymptomatic or shows very mild symptoms because the dominant allele on the other $X$-chromosome masks the effect of the recessive gene.Statement $(d)$ is incorrect: $Y$-linked genes (holandric genes) are located on the non-homologous region of the $Y$-chromosome.Statement $(e)$ is incorrect: Human males have heteromorphic sex chromosomes $(XY)$,whereas females have homomorphic sex chromosomes $(XX)$.Therefore,only statements $(a)$ and $(b)$ are correct.
