Homozygous: An organism that has an identical pair of alleles for a trait.
Hybridization: A cross between two individuals that have different traits.
Law of Independent Assortment: States that the inheritance of one trait will not affect the inheritance of another.
Law of Segregation: States that a pair of alleles is separated, or segregated, during the formation of gametes.
Linked genes: Genes that are close together on a chromosome, and are packaged into the gametes together.
