Q1. Imagine you are on the team designing a self-contained and self-sustaining base that can exist on the moon. Once supplied with building materials, equipment, and organisms from Earth, base will be expected to function indefinitely. One of leading team members has suggested that everything sent to the base be sterilized so that no bacteria of any kind are present. Do you think this is a good idea? Why or why not with specific reasons. Guess at least two of consequences eliminating all bacteria from the environment would have on the other organisms.

Q2. Albinism is a condition that results from the lack of normal pigmentation. In humans, individuals with two recessive alleles at ALBINO (aa) locus are albino.

Attached earlobes result from two recessive alleles at the (ee) EARLOBE locus.

An albino man with attached earlobes marries a pigmented woman with non-attached earlobes. They have 20 children, (the F1) none of them twins. All of their children are pigmented with non-attached earlobes.

What is the most possible genotype of woman?
