Question
Chapter 3, Problem 37P
Summary Introduction
To determine: The consistency of the progeny numbers with the results expected from the selfing a dihybrid plant of two independently assorting genes.
Introduction. The law of independent assortment was given in a dihybrid cross which is the cross between the alleles of two pairs of contrasting characters. The alleles produced by each character are independent to combine with the alleles of the other character.

How does one set up a punnet square for the following problem? I know the answer is supposed to be 3*1/2*1/4*1/4 = 3/32 but I'm not sure how we get these numbers. Please help!Question:
In the self of a polygenic trihybrid R1/r1; R2/r2; R3/r3, use the product and sum rules to calculate the proportion of progeny with just one polygene “dose.”
Two plants in a cross were each heterozygous for two gene pairs (AB /ab) whose loci are linked and
30 map units (mu) apart. (Recall that 1 mu is equal to 1% recombination between two genes.)
Assuming that crossing over occurs during the formation of both male and female gametes and
that the A and B alleles are dominant, determine the phenotypic ratio of their offspring.
Part E: What proportion of the offspring of two
plants (both (AB/ab ) will be A - B- if the genes are 30
mu apart?
Part F: What proportion of the offspring of two
plants (both (AB/ab)) will be A - bb if the genes are 30
mu apart?
Part G: What proportion of the offspring of two
plants (both (AB/ab)) will be aaB- If the genes are 30
mu apart?
Part H: What proportion of the offspring of two
plants (both (AB/ab)) will be aabb if the genes are 30
mu apart?
At the molecular level (with regard to loss-of-function alleles), explain why the ttvv homozygote has an ovate seed capsule.
