1. What percentage of the cross will be considered heterozygous? 2. What percentage of the cross will show the dominant phenotype? 1. What would the genotype of a heterozygous person be?
2. What trait would that same individual express in their phenotype? 1.

2. Explain crossing over in terms of meiosis 1. Dog somatic cells have 78 chromosomes. How many chromosomes would their gametes have?
2. What are 3 events that happen during meiosis and fertilization that lead to genetic diversity in a population? 1. What is crossing over, when does it happen?
2. What is it called when chromosomes line up on on their own, what phase is this? 1. How many cells are at the end of Meiosis?
2. How are these cell different than those resulting from Mitosis? 1. What are the two types of cells in your body?
