Title: In humans, a widow’s peak is caused by a dominant allele W, and a continuous hai
Post by: arealhero on Nov 22, 2014
In humans, a widow’s peak is caused by a dominant allele W, and a continuous hairline is caused by a recessive allele w. Short fingers are caused by a dominant allele S, and long fingers are caused by a recessive allele s. 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?
a. Female wwSS; male WWss
b. Female wwSs; male Wwss
c. Female wwSs; male WWss
d. Female WwSs; male WwSs
e. None of the above
