Solution
The correct option is A10g The genotype aabbcc is considered as homozygous recessive genotype, the genotype AABBCC is considered as homozygous dominant genotype.
The total number of alleles in each genotype is 6. The value of homozygous dominant is 160 kg, the value of homozygous recessive is 100 kg. The difference of these two values is divided by total number of alleles in each genotype to find out the contribution of each polygene as in the image.
