| Term | Definition |
|---|---|
| Genetics | scientific study of heredity and genes |
| Hereditary | the passing of genetic information and traits from parents to offspring |
| Fertilization | process in sexual reproduction in which male (sperm) and female (egg) reproductive cells join to form a new cell (zygote) |
| Trait | specific characteristic of an individual |
| Hybrid | an offspring produced by organisms that differ in genetically determined traits also known as a cross between parents of different species |
| Gene | segments of DNA that carry the instructions to make specific proteins that control a specific trait in the organism (basic unit of hereditary) |
| Allele | variation/different forms of a gene (there are TWO - dominant and recessive) |
| Principle of dominance | Mendel’s second conclusion, which states that some alleles are dominant and others are recessive |
| Segregation | separation of two alleles during gamete formation |
| Gamete | a sex cell |
| Probability | likelihood/chance that a particular event will occur |
