Vocabulary Genetics: The part of biology that focuses on heredity. Heredity: The passing of traits from parents to offspring. True breeding:If something only shows only one form of a trait after several generations of self-pollination. Parental Generation (P1): The first two individuals that cross in the breeding experiment. First Filial Generation (F1): The offspring of P1 cross. Second Filial Generation (F2) the offspring of F1 self pollinating. Homozygous: When two alleles are present and form a gene that is the same. (PP) Heterozygous: When two alleles are present are different. (Pp) Punnett Square: a diagram that predicts the outcome of a cross by showing all the possible genotypes and phenotypes. Probability: The likelihood that an event will occur. (can be expressed in words, decimals, percentages, or fractions)

Monohybrid cross: Crossing that involves only one trait.

P1 Awesome X Not Awesome AA gg F1 All Awesome Aa F2 3:1 Awesome: Not Awesome

Dihybrid Cross: Crossing that involves two traits.
