GENETICS

Mendel's Princples of Inheritance

1. The F1 generation showed only dominant traits
2. In the F2 generation, both the dominant and recessive traits reappeared
3. In the F2 generation, there were 3x as many plants with the dominant traits than plants with recessive traits

LAW OF SEGREGATION
          - Mendel inferred that the two factors determining a trait segregates when the sex cells are formed
          - Each gamete (egg cell or pollen) is equally likely to contain either traits
phenotypes: trait of a plant (tall)
genotypes: the pair of alleles for that trait (TT or Tt)

LAW OF DOMINANCE

LAW OF INDEPENDENT ASSORTMENT
          - alleles of the gene pair for a particular pair of traits segregate independently of the alleles of gene pairs for the trait
