red and homozygous dominant tall plant crossed with a heterozygous red and dwarf plant. Use the letters
R and r for fruit color, and T and t for height. (8 pts)
a. What is the phenotype ratio?
b. What percent of the offspring will be totally heterozygous?
c. What percent of the offspring will have yellow fruit and dwarf vines?
