Discussion:

Meiosis

1. How many types of telophase II products can be formed if a homozygote (AA or aa) is under study?

2. How many types of telophase II products can be formed if a heterozygote (Aa) is under study?

3. How many kinds of gametes can be formed if the genotype is AABB? Make a drawing of this type of cell in Prophase I. Label the chromosomes.

4. How many kinds of gametes can be formed if the genotype is AaBb? Make a drawing of this type of cell in Prophase I (zygotene). Label the chromosomes.

5. How does each one of the Telophase II products (one of the 4 cells in the tetrad) compare with the Prophase I cell with regard to chromosome number?
