Phenotypic ratio of a dihybrid cross |
9:3:3:1 |

Mendel's 1st law |
Independent segregation. During meiosis, half the gametes recieve one allele and the other half recieves the other allele of a given gene. |

Mendel's 2nd law |
Random assortment. For any two genes (A and B), there is random assortment so that each gamete will arbitrarily recieve one allele of each (A or a and B or b) |
|
Pleiotrophy |
When one gene influences two or more seemingly unrelated traits |
|
Epistasis |
