| incomplete dominance | The type of inheritance in which the alleles for expressing characteristics are neither dominant or recessive. |
| codominance | The expression (but not blending) of both alleles in heterozygous offspring. |
| multiple alleles | The possible arrangement of three or more genes (alleles) for a trait at a single locus. |
| dihybrid cross | A genetic cross dealing with two characteristics at the same time. |
| independent assortment | The Mendelian idea that the separation of one set of alleles during gamete formation is not affected by the separation of another set of alleles. |
| polygenic inheritance | The cumulative effect of two or more genes on the same trait. |
