in garden peas, genes controlling height, flower color, and seedsize are on the third autosome
gene map:
height-----10 mu------- color-------------20mu------ seedsize
a purebred tall, red flowered, large-seeded plant is crossedwith a purebred short, white flower, small seeded plant. All of theoffspring are medium height, pink, and small seeded.
A. What proportions of the pollen produced by the F1 will carrythe tall, red flowered and large seed alleles?

The description of F1 ie medium height pink flower and small seeded indicates that the genes for height and flower color show incomplete dominance because the phenotypes in F1 is intermediate in extremes ie medium height parents are tall and short pink flowers parents have red flowers and white flowers But the gene for seed size shows dominance of small seeds over large ones Answer A Let the genotypes for height are TT tall tt short Tt medium height See Answer
