An organism has the following genotype AABbMmCC. What are the possible gametes that could be made from this organism?

How many distinct genotypes are produced from a self cross of of the “tetrahybrid” A/a; B/b; C/c; D/d?

Considering an organism with three pairs of homologous chromosomes, how many different kinds of gametes can this organism produce based on different chromosomal arrangements? Assume that the members of each pair are not identical?

How many different types of gametes can you produce from this cell heterozygous for two genes (AaFf)? (2)

Briefly illustrate how nondisjunction in meiosis can result in Down syndrome.

Part of the karyotype of a diploid individual who is heterozygous for one chromosomal rearrangement is shown in the diagram. The chromosomes involved in the rearrangement, and their homologous pair, are shown. The location of each gene is labeled using horizontal lines and the name of each gene is labeled using letters or numbers. Answer the following questions about the diagram. A. What rearrangement is shown? Be as specific as possible. B. Describe a mutation scenario that could cause this rearrangement to be formed.

The dog Canis familiaris is a diploid organism with 39 pairs of homologous chromosomes. What is the 2n number for the dog?  What is the n number for the dog?

With two pairs of homologous chromosomes, four kinds of gametes can be produced. How many kinds of gametes can be produced with three pairs of homologous chromosomes? What does this suggest for the 23 homologous pairs of chromosomes in human cells?

List down all the possible types of gametes produced by the following individuals with genotypes: a.  AaBbccddE-

Give an example of a monohybrid cross and a dihybrid cross.
