You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus a

kramer

Answer:

28 units

Explanation:

This disorder follows quantitative inheritance. It is controlled by three genes which do not show the usual dominant-recessive relationship . The six alleles individually contribute to the effect which add up to produce the cumulative phenotype. Dominant allele contributes 6 units of risk whereas recessive allele contributes 2 units of risk.

Individual with genotype AABbCc has four dominant alleles (AABC) and two recessive alleles (bc). So their total risk units =

(6*4) + (2*2) = 24 + 4

= 28 units
