In pea plants p represents purple flowers while p represent white, and t represents tall plants while t represents short. biologist cross two pea plants, each of the genotype pptt. we would expect what phenotypic ratio from this dihybrid cross?

The expected phenotypic ratio is 9:3:3:1.

As per the question, purple (P) and tall (T) are the dominant traits over white (p) and short (t), which are recessive traits.

Pea plants with parental genotype PpTt will produce 4 types of gametes that is PT, Pt, pT, and pt. When the parents ( with genotype PpTt) are crossed with each other, they will produce four different types of phenotypes that is illustrated in the punnett square.
