Vedclass · Answer

(B) $1$. The man has brown eyes and red hair. Since brown is dominant $(B)$ and red hair is recessive $(d)$, his genotype must be $B_dd$. Since he has a child with blue eyes $(bb)$, he must carry the recessive allele for blue eyes. Therefore, the man's genotype is $Bbdd$.
$2$. The woman has blue eyes and dark hair. Since blue eyes are recessive $(bb)$ and dark hair is dominant $(D)$, her genotype must be $bbD$. Since she has a child with red hair $(dd)$, she must carry the recessive allele for red hair. Therefore, the woman's genotype is $bbDd$.
$3$. Thus, the genotypes are $Bbdd$ for the man and $bbDd$ for the woman.
