Suppose there are five genes in pumpkins that work additively to affect pumpkin size. A homozygous lowercase allele pumpkin, aabbccddee, weighs 20 lb. Each capitalized allele additively affects the final phenotype by either adding or subtracting weight from the base pumpkin size. The effect of a single capitalized allele is listed in the table. AlleleEffect A +6 B −2 C −3 D +3 E +4 What would the potential size range be for pumpkin offspring produced from the cross between a parent with genotype aaBbCCDdEe and a parent with genotype AaBBCcddEe?
