| Mendel's Laws | the basic rules of inheritance |
| What didn't Mendel know about yet? | Chromosomes and genes |
| alleles | different versions of a gene for the same trait (T, t are alleles of height) |
| Law of Segregation | Factors separate when gametes form: each pair of alleles segregates during meiosis. |
| Law of Dominance | when the 2 alleles in a gene pair are different (hybrid), one allele can control the trait, and the other is hidden |
| Law of Independant Assortment | Gene pairs segregate into gametes randomly and independent of each other. |
| genotype | the actual genetic makeup of an organism (shows both traits) |
| phenotype | the form of the trait being observed (expressive - dominant - trait) |
| homozygous | in an organism, when 2 alleles for a trait are identical (TT or tt) |
| heterozygous | in an organism, when 2 alleles for a particular trait are not identical (Tt) |
