Sex-linked recessive

Vedclass · Answer

(C) $1$. The parents are unaffected,which suggests that the disease is recessive. $2$. The disease appears only in sons ($3$ out of $5$) and not in daughters. $3$. This pattern of inheritance,where the trait is passed from a carrier mother to her sons,is characteristic of $X$-linked recessive inheritance. $4$. In $X$-linked recessive disorders,males are more frequently affected because they have only one $X$ chromosome. If the mother is a carrier $(X^CX)$,she can pass the affected $X$ chromosome to her sons,who will then express the disease $(X^CY)$.

$A$ man and a woman who do not show any apparent symptoms of certain genetic diseases have seven children ($2$ daughters and $5$ sons). Three of the sons suffer from the given disease,but none of the daughters are affected. Which type of inheritance pattern do you suggest for this disease?
