Lesson: Dihybrid Inheritance Biology • First Year of Secondary School

In this lesson, we will learn how to construct and interpret genetic diagrams of dihybrid crosses.

Lesson Plan

Students will be able to

recall that alleles for different characteristics are inherited independently of each other,
explain what is meant by dihybrid inheritance,
determine the alleles produced from a given genotype,
interpret Punnett squares that show dihybrid crosses,
state phenotypic ratios of these crosses.
