1) The following is a false statement. Explain why and give a specific example to support your reasoning.

"Upon solving a Punnet square, the genotype ratio and phenotype ratio values are always the same".

2) Explain the meanings of, and relationships between, the following 6 terms: gene, locus, allele, genotype, pleiotropy, phenotype.

3) What does it mean to be a carrier for a trait? How does the chance of being a carrier change if you are talking about the genotypes for an X-linked trait?

4) What is a "gene pool"? How does this relate to genetic drift and gene flow?

5) Suppose you sample 100 snails: 20 are small, 60 are medium size, and 20 are large. Explain how these observations would vary (give specific numbers) if this population over time was changed due to directional, disruptive, and stabilizing selection. Your answer should clearly teach me the differences in these selection concepts.
