| genetics | study of heredity |
| true breeding | self pollination in a yellow pea plant will produce a yellow pea plant |
| gene | chemical factor that determines a trait |
| allele | forms a gene may take |
| hybrid | combination of two different alleles |
| segregation | separation of alleles |
| gametes | Sex cells are referred to as |
| probability | likelihood that a particular event will occur |
| trait | characteristic or feature passed on to offspring |
| genotype | Genetic makeup of an organism |
| phenotype | Physical characteristics of an organism |
| homozygous | an organism that has two identical alleles for a particular trait |
| heterozygous | an organism that has two different alleles for the same trait |
| recessive trait | Trait that can only be seen with homozygous alleles |
| dominant trait | Trait that blocks a recessive trait from being seen |
| punnett square | Diagram showing the gene combination that might result from genetic cross |
| independent assortment | Independent segregation of genes during the formation of gametes |
| incomplete dominance | Situation in which one allele is not completely dominant over another |
| diploid | cell that contains both sets of homologous chromosomes |
| haploid | cell that contains only a single set of chromosomes and therefore only a single set of genes |
