Chapter 5, Problem 27P

In tomatoes, the allele $\text{T}$ for tall plant height is dominantto dwarf allele $\text{t}$, the $\text{P}$ allele for smooth skin is dominant to the $\text{p}$ allele for peach fuzz skin, and the allele $\text{R}$ for round

fruit is dominant to the recessive $\text{r}$ allele for oblong fruit. The genes controlling these traits are linked on chromosome $\text{1}$ in the tomato genome, and the genes are arrangedin the order and with the recombination frequenciesshown.

A $\text{pure-breeding}$ tall, peach fuzz, round plant is crossedto a $\text{pure-breeding}$ plant that is dwarf, smooth, oblong. What are the gamete genotypes produced by each ofthese plants?

What are the genotype and phenotype of the $\text{F1}$ progeny of this cross?

What are the genotypes of gametes produced by the $\text{F1}$, and what is the predicted frequency of eachgamete?

The $\text{F1}$ are $\text{test-crossed}$ to dwarf, peach fuzz, oblong plants, and $\text{1000 test-cross}$ progeny areproduced. What are the phenotypes of $\text{test-cross}$ progeny, and what number of progeny is expected ineach class?
