=Genetics and Heredity =

 **Genetics** -- The science of heredity and of the mechanisms by which traits are passed from parents to offspring.  **Heredity** -- The passing of genetic traits from parent to offspring.  **Monohybrid Cross** -- A cross between individuals that involves one pair of contrasting traits.  **Dihybrid Cross** -- A cross between individuals that involves two pairs of contrasting traits. **True Breeding** -- Allowing a plant to self-pollinate for several generations.  **P Generation** -- The first two individuals that are crossed in a breeding experiment.  **F1 Generation** -- The first generation of offspring obtained from an experimental cross of two organisms. F1 meaning Filial  **F2 Generation** -- The second generation of offspring, obtained from an experimental cross of two organisms; the offspring of the F1 generation. F2 meaning Filial 2.  **Homozygous** -- describes an individual that has identical alleles for a trait on both homologous chromosomes.  **Heterozygous** -- describes an individual that has two different alleles or traits.
