Dihybrid Crosses Punnett Squares involving 2 Traits Block. Determine letters you will use to specify traits. A dihybrid cross tracks two traits.

These two traits are independent of each other. Dihybrid cross calculator allows you to compute the probability of inheritance with two different traits and four alleles all at once. Determine letters you will use to specify traits.

Suppose that black hair B is dominant over blonde hair b and brown eyes E are dominant over blue eyes e. But in the cross above one parent can only form two types of gametes. This two-trait Punnett square will allow you to calculate both the phenotypic and genotypic ratio of the dihybrid cross.
