| trait | specific characteristic of an individual |
| independent assortment | one of Mendel’s principles that states that genes for different traits can segregate independently during the formation of gametes |
| probability | likelihood that a particular event will occur |
| Punnett Square | diagram that can be used to predict the genotype and phenotype combinations of a genetic cross |
| codominance | situation in which the phenotypes produced by both alleles are completely expressed |
| incomplete dominance | situation in which one allele is not completely dominant over another allele |
| multiple alleles | a gene that has more than two alleles |
| polygenic trait | trait controlled by two or more genes |
| principle of dominance | Mendel’s second conclusion, which states that some alleles are dominant and others are recessive |
| segregation | separation of alleles during gamete formation |
