Homozygous means ________.
having no genes
having non-identical pairs of genes for any pair of hereditary characteristics, ex: Yy, yY
having pairs of genes
having identical pairs of genes for any pair of hereditary characteristics, ex: YY, yy
Heterozygous means ________.
having non-identical pairs, not the same, genes for any pair of hereditary characteristics, ex: Yy, yY
having identical pairs, the same, genes for any pair of hereditary characteristics, ex: YY, yy
having genes
having special genes that are called hetero
What is a genotype?

Law of Seperation
Law of Independent Assortment
Law of Segregation
Law of the Punnett Square
