Hey! Here's your new scribe.

Mendel's law of independent assortment:

  • Genes for different traits are inherited independently of one another.
  • The alleles can combine in different ways.

Example: TT, Tt, tt

-Mendel crossed pure-bred tall and pure-bred short pea plants.

-The offspring Mendel referred to as a hybrid, often called a "mutt'', it is the offspring of parents with different forms of trait.

-Mendel's F2 Generation led to his discover of a factor being passed through the generation.

-In 1905 Ronald Punnett discovered a way to predict expected gentotypes offspring.

  • Phentotypic ratio- 3 tall: 1 short
  • Genotypic ratio- 1TT: 2Tt: 1tt
  • Homozygous means same such as TT or tt.
  • Heterozygous means different sach as Tt.

-Taylor will be the new scribe!
