| A | B |
|---|
| Codominace | both alleles for a gene are expressed in a heterozygous offspring |
| Complete dominance | one allele is completely dominant over another plants are indistinguishable in phenotype. |
| Dihybrid cross | cross between individuals that involves 2 pairs of contrasting traits |
| Genotype | genetic make of an organism consists of the alleles that are inherited from parents |
| Genotype ratio | ratio of the genotypes that appear in offspring |
| Heterozygous | two alleles in a pair are different |
| Homozygous | when both alleles of a pair are alike |
| Incomplete dominance | offspring will have a phenotype in between the parents |
| Monohybrid cross | cross between individuals that involves one pair of contrasting traits |
| Phenotype | appearance of an organism as a result of its genotype |
| Phenotypic ratio | the ratio of the offspring’s phenotype |
| Probability | the likelihood that a specific event will occur |
| Punnett square | used to predict the probability that certain traits will be inherited by offspring |
| Testcross | an individual of unknown genotype is crossed with a homozygous recessive individual |
