What percentage of homozygous $R h^{-i i}$ will be born amongst four children of a couple where the husband is heterozygous for $R h^{+i i}$ and wife is homozygous for $R h^{-i i}$ gene?

$25\, \%$

$50\, \%$

$75\, \%$

$100\, \%$

Solution

The husband is heterozygous for $R h^{+i i}$ so, it will $(Rh\, rh)$ and wife is homozygous of $R h^{-i i}$ so, it will have genetic alleles $(rh\, rh):$

So, $50 \%$ homozygous $R h^{-i i}$ children will be born.
