Question
Assume three loci, each with dominance (A>a, B>b, C>c), contribute to weight in pumpkins. Assume as well that each locus contributes equally to weight. Pumpkins that are homozygous reccessive weigh 3 pounds and those homozygous dominant at all three loci weigh approximately 300 pounds. What is the weight of a pumpkin with the following genotype? aaBbCC. Show work.
a) 51 lbs
b) 101 lbs
c) 151 lbs
d) 201 lbs
e) 251 lbs
Explanation / Answer
It states that all 3 loci play *equal* role in the weight. Therefore, it is reasonable to conclude that every loci is responsible for 100 lbs each, where XX = 100 lbs, and xx = 1 pound. It can be safe to assume that Xx = 50 bounds X>x Now aa = xx = 1 pound Bb = Xx = 50 pound CC = XX = 100 pound 100+50+1 = 151 lb c) 151 lbs
