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
