Q1. A typical prokaryotic cell has about 3,000 genes in its DNA, even as a human cell has about 25,000 genes. About 1,000 of these genes are present in both types of cells. Based on the understanding of evolution, describe how such different organisms might have this same subset of genes. What sorts of functions may these shared genes have?

Q2. If one assumes that Hardy-Weinberg equilibrium applies to population of colonists on this planet, about how many people will have attached ear lobes at what time the planet’s population reaches 10,000?
