1. Describe the stages of meiosis.
33. Solve a Punnett Square for a monohybrid cross of parental strains GG (green pea pods) crossed
with gg (yellow pea pods). What are the F1 generation genotype and phenotype? What are the
F2 generation (self-pollination or cross pollination of F1 offspring) genotypes and phenotypes.
For the phenotypes, give the expected ratios. (You can do this in Excel and upload it as an
additional file, or email it to me.)
34. Solve a Punnett Square for a dihybrid cross (2 genes) of parental strains GGTT (green pea pods
and tall plants) crossed with ggtt (yellow pea pods and short plants). What are the F1
generation genotype and phenotype? What are the F2 generation (self-pollination or cross
pollination of F1 offspring) genotypes and phenotypes. For the phenotypes, give the expected
ratios. (You can do this in Excel and upload it as an additional file, or email it to me.)

Introduction 

Meiosis is a unique form of germ cell division that creates gametes, such as sperm or egg cells, in sexually reproducing animals. Two rounds of division are necessary, and the end result is four cells with only one copy of each chromosome (haploid).

Additionally, each chromosome undergoes genetic material cross-pollination between the paternal and maternal copies before division, resulting in novel combinations of the genetic code on each chromosome. Later, when a male and a female go through meiosis, the haploid cells they generate unite to form the zygote, another cell with two copies of each chromosome.
