Essay

Use the following to answer questions
The height of a type of bean plant is determined by five unlinked genes called A, B, C, D, and E. Each gene has two alleles: additive (uppercase letter) and nonadditive (lowercase letter). The shortest plants are 130 cm. The tallest plants are 220 cm. The genotypes are known for two bean plants. Plant 1 is genotype AABbccDdEE. Plant 2 is genotype aaBBCcDdEE.
-a. Estimate how many centimeters each allele contributes to the height difference of 90 cm.
b. The genotypes are known for two bean plants. Plant 1 is genotype AABbccDdEE. Plant 2 is genotype aaBBCcDdEE. What are their heights?
c. If the two plants in the previous question are crossed, could they produce a plant that is taller than either parent? How?
d. All the genes are unlinked. Determine the probability of an AbcdE gamete from plant 1 and an aBcdE gamete from plant 2.
e. What will be the genotype and phenotype of a plant from these gametes, and what is the probability of a plant with this genotype?
f. If the progeny plant from the cross in the previous question was only 60 cm because of an allele in a gene other than A-E, what genetic phenomena are at work?
g. If the progeny plant with the genotype in part (d) was a few centimeters taller than your prediction, how would you explain it?
