In kumquat trees, plant height is determined by 3 genes as in our simplified model of polygenic inheritance. Each locus has a contributing allele and non-contributing allele. A tree with the genotype AABBCC grows to be 100 cm tall. The other homozygote grows to be 40 cm tall. What is the contribution for each contributing allele?
Determine the limit of kumquat tree height in the offspring of the crosses listed below:
Cross Minimum Height Maximum Height
AABBCc x aaBBcc
aaBbcc x AabbCc
AaBBcc x AabbCc
AaBbCC x AaBbCc
