Answer:
The % of children with webbed digits is
%
Explanation:
Given -
Syndactyly or webbed digits are due to the presence of a dominant allele (S). Then the allele for normal digits would be represented by allele "s"
A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"
If we cross Ss and ss , then the following offspring are produced -
Ss * ss
Ss, Ss, ss, ss
Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is
%
