Genetics | Study of how traits are passed from parents to offspring |

Hybrid | when the two alleles are different - another name for heterozygous |
Recessive trait | Genetic factor that is blocked by the presence of a dominant factor |
Allele | Different form of a gene |
Codominance | Occurs when both alleles can be observed in the offspring's phenotype |
Gene | Section on a chromosome that has genetic information for one trait |
Genotype | Two alleles that control the phenotype of a trait (letters) |
Heterozygous | If the two alleles of a gene are different |
