Answer:

Immunity to Small Pox

Explanation:

Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

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
