Shortcut Methods

Dihybrid Cross

1. Two Traits Studied: Involves inheritance of two different traits.

2. Alleles: Each trait has two alleles (dominant and recessive).

3. Independent Assortment: Traits inherited independently of each other.

4. Parental Genotypes: Identify genotypes of two parental organisms.

5. Gametes: Determine possible gametes for each trait.

6. Punnett Square: Use a 4x4 Punnett square to predict offspring genotypes.

7. Genotypic/Phenotypic Ratios: Analyze the Punnett square for these ratios.

8. Results Interpretation: Understand the inheritance patterns of traits.
