Solve this problem using the rules of probability instead of Punnet squares, bifurcation forks, or mental visualization. Flower position, stem length, and seed shape were three of the traits that Mendel studied. Each is controlled by an independently assorting gene and has dominant and recessive expression as follows: • Axial inflorescence (flowers originate along the stems) is dominant over terminal (flowers on top of the stem). Long (“tall") stem is dominant over short stem (“dwarf"). • Round seed is dominant over wrinkled. Let's use the symbols Fa/fa for genes determining axial vs. terminal (fa from "false umbel," a type of inflorescence); Le/le for tall vs. dwarf (le is for length); R/r for round vs. wrinkled seeds (the Latin word rugosus means wrinkled). Notice that the phenotype "tall plant" may be conferred by the genotype Lele or Lele; this can be abbreviated as Le-, where the dash represents the alternative allele. The homozygous lele will show the recessive phenotype. Since…

a. 1 dominant allele will contribute 120/10 = 12 cm to the base height of the plant.b. The height of the parent plant 1 Genotype of the parent plant 1 – D1D1D2D2D3D3d4d4d5d5 The height of the parent plant 2 Genotype of the parent plant 2 – d1d1d2d2d3d3D4D4D5D5Contributing alleles – D4D4D5D5. The height of the plant without any contributing alleles would be 80 cm. The plant with genotype d1d1d2d2d3d3D4D4D5D5 has 4 contributing allele each of which contributes 12 cm to the base. Hence, the height of the plant with genotype d1d1d2d2d3d3D4D4D5D5 would be 80 + 12 + 12 + 12 + 12 = 128 cm. c.
