Loppins (Fictitious Diploid Invertebrates)have Variable Numbers of Dots on Their

question 28

Multiple Choice

Loppins (fictitious diploid invertebrates) have variable numbers of dots on their abdomen.This variability is entirely due to genetics,with no influence of the environment,so the broad-sense heritability for this trait is 1.The mean number of dots per individual in a large population is 37.A breeder crosses the two animals with the highest number of dots,45.In the progeny,the mean number of dots is 43.4.These results suggest that the phenotype of interest is controlled:

• A)at least partly by genes that have an additive mode of action.
• B)at least partly by genes that have a dominant mode of action.
• C)by genes that have both an additive and a dominant mode of action.
• D)only by genes that have an additive mode of action.
• E)only by genes that have a dominant mode of action.
