Vedclass · Answer

(C) Let the allele for brown eyes be $B$ (dominant) and the allele for blue eyes be $b$ (recessive).$1$. The woman has blue eyes,so her genotype must be $bb$.$2$. The man has brown eyes,so he must have at least one $B$ allele. Since his mother had blue eyes $(bb)$,he must have inherited one $b$ allele from her. Thus,his genotype is $Bb$.$3$. The cross is $bb 	imes Bb$.$4$. The possible offspring genotypes are $Bb$ (brown eyes) and $bb$ (blue eyes) in a $1:1$ ratio.$5$. Therefore,$50\%$ of the children will have brown eyes and $50\%$ will have blue eyes.

In humans,blue eye color is recessive to brown eye color. If a blue-eyed woman marries a brown-eyed man whose mother had blue eyes,what will be the expected eye color of their children?
