(B) Hypertrichosis is a $Y$-linked trait,meaning the gene is located on the $Y$ chromosome.In humans,males have $XY$ chromosomes and females have $XX$ chromosomes.$A$ father passes his $Y$ chromosome only to his sons,while he passes his $X$ chromosome to his daughters.Since the daughter receives an $X$ chromosome from her father and an $X$ chromosome from her mother,she does not inherit the $Y$ chromosome.Therefore,$0\;\%$ of the daughters will have hairy ears.

$A$ $Y$-linked gene is responsible for hypertrichosis (long hair on ears). When an affected man marries a normal woman,what percentage of their daughters would be expected to have hairy ears (in $;\%$)?
