| Term | Definition |
|---|---|
| Law of Segregation | states that each set of homologous chromosome randomly separate during meiosis, leading to new genetic combinations |
| Homozygous | individuals with the same alleles, ex. AA |
| Heterozygous | individuals with different sets of alleles, ex. Aa |
| Alleles | The different forms (i.e. versions) of a gene, ex. blue eyes and brown eyes. |
| Dominant | always expressed the trait (e.g. DD or Dd) |
| Recessive | needs both alleles to express the trait, more rare (e.g. dd) |
| Gene | section of DNA that codes for a trait, ex. eye color |
| Offspring | the next generations, the "babies, pups, etc." |
| Meiosis | cell division that starts with 2N ends with 1N |
