Question

Suppose a woman with a continuous hairline and short fingers and a man with a widow’s peak and long fingers have three children. One child has short fingers and a widow’s peak, one has long fingers and a widow’s peak, and one has long fingers and a continuous hairline. What are the genotypes of the parents

Answer 1

Answer:

The women has a genotype of hhff and the man has a genotype of HhFf

Explanation:

From the results of the children we can see that widows peak and long fingers are dominant because it has the majority in the family. The question is are the parents homozygous dominant. The are not. They are heterozygous because if they were homozygous they wouldn’t be able to have any recessive genes transfer to the children
