1. How does meiosis generate genetic diversity?
a) crossing over
b) random alignment at metaphase I
c) synapsis
d) both crossing over and random alignment at metaphase I
2. What would happen if crossing over occurred between sister chromatids?
a) Genetic diversity would decrease due to the loss of gene combinations.
b) Genetic diversity would increase due to the addition of gene combinations.
c) Gene rearrangement would lead to changes in gene expression.
d) Nothing would happen becasue sister chromatids are genetically identical or nearly identical.
3. Animals that sexually reproduce are _____ and produce _____ gametes. (haploid, diploid; haploid, haploid; diploid, diploid; diploid, haploid)
4. The F1 generation of a cross between two individuals, one that is homozygous dominant for a trait and the other that is homozygous recessive for the trait, will yield progeny with the same phenotype. (true or false)
5. Homologous chromosomes separate from each other in:
a) mitosis
b) meiosis I
c) meiosis II
d) They never separate from each other during any form of cell division
