| Heredity | |
| Trait | |
| Genetics | |
| Fertilization | a complex multi-step process that is complete in 24 hours |
| Purebred | offspring resulting from a true breeding |
| Gene | the basic physical and functional unit of heredity. |
| Allele | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. |
| Dominant allele | only one copy of the dominant allele is required to express the trait. |
| Recessive allele | does not produce a trait at all when only one copy is present |
| Hybrid | an offspring of two animals or plants of different subspecies, breeds, varieties, species, or genera. |
| Punnett square | is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. |
| Phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| Genotype | the genetic constitution of an individual organism. |
| Homozygous | having inherited the same versions (alleles) of a genomic marker from each biological parent. |
| Heterozygous | A term that describes having two different versions of the same gene |
| Incomplete dominance | a genetic phenomenon where one allele does not completely mask the effects of another when both are present in a heterozygous individual |
| Codominance | a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual. |
| Multiple alleles | the presence of three or more alternative forms of a gene at a specific locus within a population |
| Polygenic inheritance | occurs when one characteristic is controlled by two or more genes. |
| Messenger RNA | A type of RNA found in cells. |
