2 Punnett Percentage Practice (#1) ___ ___ AA = Aa = aa = Offspring Phenotype Chance (%) Dominant Trait = Recessive Trait = Offspring Genotype Chance (%) ___ Parent 1 Genotype: AA Parent 2 Genotype: aa

3 Punnett Percentage Practice (#1) Aa _A_ _A_ AA =0 Aa = 100 aa =0 Offspring Phenotype Chance (%) Dominant Trait =100 Recessive Trait = 0 Offspring Genotype Chance (%) _a_ Parent 1 Genotype: AA Parent 2 Genotype: aa

4 Punnett Percentage Practice (#2) ___ ___ AA = Aa = aa = Offspring Phenotype Chance (%) Dominant Trait = Recessive Trait = Offspring Genotype Chance (%) ___ Parent 1 Genotype: AA Parent 2 Genotype: Aa

5 Punnett Percentage Practice (#2) AA Aa _A_ _A_ AA =50 Aa = 50 aa =0 Offspring Phenotype Chance (%) Dominant Trait =100 Recessive Trait = 0 Offspring Genotype Chance (%) _A_ _a_ Parent 1 Genotype: AA Parent 2 Genotype: Aa

6 Punnett Percentage Practice (#3) ___ ___ AA = Aa = aa = Offspring Phenotype Chance (%) Dominant Trait = Recessive Trait = Offspring Genotype Chance (%) ___ Parent 1 Genotype: Aa Parent 2 Genotype: Aa

7 Punnett Percentage Practice (#3) AAAa aa _A_ _a_ AA =25 Aa = 50 aa =25 Offspring Phenotype Chance (%) Dominant Trait =75 Recessive Trait = 25 Offspring Genotype Chance (%) _A_ _a_ Parent 1 Genotype: Aa Parent 2 Genotype: Aa

8 Punnett Percentage Practice (#4) ___ ___ AA = Aa = aa = Offspring Phenotype Chance (%) Dominant Trait = Recessive Trait = Offspring Genotype Chance (%) ___ Parent 1 Genotype: Aa Parent 2 Genotype: aa

9 Punnett Percentage Practice (#4) Aaaa Aaaa _A_ _a_ AA =0 Aa = 50 aa =50 Offspring Phenotype Chance (%) Dominant Trait =50 Recessive Trait = 50 Offspring Genotype Chance (%) _a_ Parent 1 Genotype: Aa Parent 2 Genotype: aa

10 Punnett Percentage Practice (#5) ___ ___ AA = Aa = aa = Offspring Phenotype Chance (%) Dominant Trait = Recessive Trait = Offspring Genotype Chance (%) ___ Parent 1 Genotype: AA Parent 2 Genotype: AA

11 Punnett Percentage Practice (#5) AA _A_ _A_ AA =100 Aa = 0 aa =0 Offspring Phenotype Chance (%) Dominant Trait =100 Recessive Trait = 0 Offspring Genotype Chance (%) _A_ Parent 1 Genotype: AA Parent 2 Genotype: AA

Punnett Square Notes. Crossing Traits We use Punnett Squares to cross parents traits. This gives us a percentage to be able to determine an offspring’s.
