Answer:

3/8

Explanation:

Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).

Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).

This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes

So, martha's alleles are: Ww and ee.

If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are

Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee
