| Question |
Answer |
| genotype | A organism’s genetic combination |
| dihybrid cross | fertilization between two organisms to study two different traits. |
| monohybrid cross | fertilization between two organisms to study one trait. |
| heterozygous | having non identical alleles for a trait |
| homozygous | having identical alleles for a trait. |
| phenotype | outward appearance of an organism |
| probability | the likelihood a specific event will occur |
| Punnett Square | A diagram used to predict possible genetic outcomes |
| genotypic ratio | The ratio of genotypes |
| phenotypic ratio | the ratio of phenotypes |
| testcross | when an individual of unknown genotype is crossed with a homozygous recessive. |
| complete dominance | When a dominant allele masks the recessive. |
| incomplete dominance | When both alleles have an intermediate amount of expression and neither is strong enough to mask the other |
| codominance | Neither allele is intermediate-both are expressed at once, like spots. |
