1. There are 44 chromosomes in rabbit’s germ cell. There are 8 alleles for a certain gene in the rabbit population. How many different alleles for this gene could be present in a single rabbit spermatozoid? (my answer: 1)

2. There are 48 chromosomes in each somatic cell of a gorilla. There are 2 alleles for a certain gene in the gorilla population. How many different alleles for this gene could be present in a single cell in meiosis II anaphase? (my answer: 2)

3. What are homologous chromosomes? ( my answer: chromosomes carry the same genes, and pair with each other during meiosis)

4. A diploid somatic cell from a rat has a total of 42 chromosomes. As in humans, sex chromosomes determine sex. What is the total number of DNA molecues in a rat cell in G2? ( my answer: 42)

5. In terms of “non disjunctions” and meiosis stages, what result in a human somatic cell having only one alleles copy of genes? ( My answer:non disjunction during meiosis I)
