Part 2: Dihybrid Cross—Predicting Flower Color and Seed ShapeImagine that you are crossing two plants that are heterozygous for flower color and seed shape. The dominant and recessive alleles for these traits are as follows:purple flowers: Pwhite flowers: pround seeds: Rwrinkled seeds: r1. How will the alleles for these traits assort into the gametes that each parent might produce?Parent plant 1Gamete 1:Gamete 2:Gamete 3:Gamete 4:Parent plant 2Gamete 1:Gamete 2:Gamete 3:Gamete 4:

Respuesta :

Cross between two heterozygous plants (Dihybrid cross): PpRr x PpRr

Punnet square

The two-letter alleles found outside the square are the gametes of the parents. These gametes are PR, Pr, pR, and pr. Both parents have the same set of gametes since they are both heterozygous individuals.

The visual representation of getting the gametes of parents can also be done using the following method:

PARENT 1 PpRr

Gamete 1: PR

Gamete 2: Pr

Gamete 3: pR

Gamete 4: pr

PARENT 2 PpRr

Gamete 1: PR

Gamete 2: Pr

Gamete 3: pR

Gamete 4: pr
