Mendelian Genetics
In tomato plants, the gene R has two alleles that control fruitcolor: the R allele is dominant and produces red tomatoes; ther allele is recessive, and when homozygous produces yellowtomatoes. Gene T controls plant height: the T allele isdominant and produces tall plants; the t allele isrecessive and when homozygous produces dwarf plants. Genes R and Tundergo independent assortment.
A. Parental tomato plants of genotypeRRTT and rrtt are crossed. What genotype andphenotype do you expect in the F₁ generation?
B. The F₁ tomatoes are interbred.Draw a Punnett Square to predict the genotypes and phenotypes thatwill be seen in the F₂ generation. Why is this only aprediction?
C. What fraction of the F₂ generationis expected to be purebreeding?
D. Would you expect to see the same or differentresults if the parental tomato plants had genotypes RRttand rrTT?

AS the parental genotypes RRTT and rrtt are crossed we get theF1 progeny as RrTt which means tall plants with red tomatoes InF1 genration the alleles for See Answer
