| genetics | science of inheritance of traits from one generation to the next |
| Mendel | monk whose studies of pea plants led to modern genetics |
| purebred | an organism that always produces offspring with the same form of traits in its offspring |
| crossbred | an organism that produces different forms of traits in its offspring |
| stamens | part of flower that produces the pollen |
| pistil | part of flower that will produce the seed |
| gene | the DNA that determines a trait |
| chromosome | a "body" within the cell nucleus containing many genes for many different traits |
| allele | different forms of a specific gene |
| heterozygous | having different alleles of the gene |
| homozygous | having the same alleles of the gene |
| dominant | an allele that will express its trait whether homozygous or heterozygous |
| recessive | an allele that will express its trait only in the homozygous trait |
| phenotype | how the organism looks, this can be expressed with an adjective |
| genotype | the actual genes for the trait that the organism has |
| P1 | the parent generation |
| F1 | the first generation of a cross or mating |
| F2 | the second generation produced by a cross or mating |
| Pungent Square | a chart method used to predict the probability of genetic combinations and traits |
| codominance | a situation in which alleles are neither dominant or recessive |
