Question1: A pure-breeding tall, peach fuzz, round plant is crossed to a pure-breeding plant that is dwarf, smooth, oblong. What are the gamete genotypes produced by each of these plants?
D. The tall, peach fuzz, round plant will produce TPR gametes. The pure-breeding dwarf, smooth, oblong plant will produce tpr gametes.
Question2: A pure-breeding tall, peach fuzz, round plant is crossed to a pure-breeding plant that is dwarf, smooth, oblong. What are the gamete genotypes produced by each of these plants?
C.The F1 are tall, smooth, round and have the genotype TpR/tPr.
Question3: A pure-breeding tall, peach fuzz, round plant is crossed to a pure-breeding plant that is a dwarf, smooth, oblong. What are the gamete genotypes produced by each of these plants?
B. 39.2%TpR, 39.2%tPr, 0.8%Tpr, 0.8%tPR, 9.8%TPr, 9.8%tpR, 0.2%TPR, and 0.2%tpr.
In tomatoes, the allele T for tall plant height is dominant to dwarf allele t, the P allele for smooth is dominant to the p allele for peach fuzz skin, and the allele R for round fruit dominant to the recessive r allele for oblong fruit. The genes controlling these traits are linked on chromosome 1 in the tomato genome, and the genes are arranged in the order and with the recombination frequencies shown:
Gene T P R
Recombination _____.02____.02__
