  1. Punnett Squares

  2. Monohybrid Crosses • A punnett square that examines only one trait at a time. • Shows the probability of the traits of offspring. • Set up of a monohybrid cross Parent 1 Genotype Parent 2 Genotype

  3. Example Monohybrid Cross Mendel breed a heterozygous tall pea plant and a heterozygous tall pea plant. Probabilities:

  4. Dihybrid Cross • A punnett square that examines two traits at one time • Shows the probability of two traits of the offspring • Set-up of dihyrid cross Parent 1 Genotype Parent 2 Genotype

  5. Example of Dihybrid Cross Mendel cross one garden pea plant heterozygous for height and seed shape with a garden pea plant heterozygous for height and seed shape
