Overview
1. Draw the cell on the right (note that the letters indicate the gene and alleles present in each chromosome, show those letters on every drawing) as it goes from the G1 phase, to the S phase, G2 and then every phase in meiosis. Indicate the main things that happen to its chromosomes at each stage (label: sister chromatids, homologous chromosomes, Meiosis I, Meiosis II, identify which cells are haploid and which are diploid). Draw it in paper and upload a photo or scan, post it as an image not as a file to the discussion post (use the image icon to upload).

2. Based on the diagram you drew above: A) Which events are unique to meiosis. B) The main purpose of sexual reproduction is to produce genetic variation in the offspring. Explain at least 3 ways in which meiosis promotes genetic variation. C) Explain which events in meiosis are responsible for the principle on segregation and which events are responsible for the principle of independent assortment.

5. For the pedigree on the right, individuals affected with the genetic condition are indicated by the shaded symbols. A) Based on this pedigree, what type of inheritance does this genetic condition have (dominant, recessive, sex-linked)? Explain. B) What is the genotype of the parents? C) What makes an allele dominant or recessive?
