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.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
