697667826 | Hybrid Traits | a trait where one gene dominates a recessive gene and the dominant triat is visible and the recessice one is not. the parent can pass along the recessive trait to their children, where if paired with another recessive gene, the recessive trait WILL be visible | 24 | |
697667828 | Chromosomes | cell structures that carry hereditary information | 25 | |
697667830 | Genes | short segments of DNA information, within chromosomes, that serve as a code for bits of hereditary information | 26 | |
