You are studying a disorder that is based on the genetic composition at three loci. Assume that a dominant allele at any locus adds 5 units of risk for the disorder and that a recessive allele at any locus adds 3 units of risk for the disorder. Individuals with 26 or more units of risk develop the disorder. The environment does not affect the presence or absence of this disorder. How many risk units will be present in an individual of genotype AABbcc

Answer:

24

Explanation:

Given that:

At either locus, the expression of the dominant allele increases the risk by 5 units.

The assigned genetic sequence "AABbcc" has three dominant alleles, implying that it increases risk by 15 units.

At any locus, the expression of the recessive allele increases the risk by three units. The assigned genetic sequence "AABbcc" has three recessive alleles, which means it increases the chance by 9 units.

In an individual with the genotype AABbcc, the total number of risk units is = 15+9 = 24. This implies that the person does not develop the disease).
