Answer:
1/2 or 50%
Explanation:
Given that the extra digit is a dominant trait, the man with an extra digit may be homozygous or heterozygous dominant for the trait.
However, having a daughter with his normal wife makes him heterozygous dominant. Let's assume that the genotype of the heterozygous dominant male is "Dd" and that of his wife is "dd".
The heterozygous dominant male and homozygous recessive female would have progeny in the following ratio= 1/2 Dd (child with extra digit): 1/2 dd (child with no extra digit).
Answer: it is D
Explanation: if you get a gene from your parents it's a gene you get it's not a mutation because if it was it would've been like a calico color but since it's just black it's D.
You should draw a punnet square and get 50% heterozygous
Unlike New World monkeys, hominines D. Have opposable thumbs
Opposable thumbs refers to the structure of thumbs that allow the thumb to move around more freely and able to touch all other fingers.
The hominines had these type of thumbs which help them had the ability to clib trees faster in order to survive in their environment
