Alleles of different traits are inherited independently.

What educational tool did Reginald C. Punnett create?

Punnett square.

What is the objective of Lab Act 3 about Mendel’s laws?

What ratios are predicted in monohybrid crosses?

Genotypic and phenotypic ratios.

What is the classic phenotypic ratio of a dihybrid cross?

9:3:3:1.
