Assume a population of pigs is at mutation selection equilibrium. Which trait should have the lowest heritability?

Group of answer choices

back fat thickness

pig body length

big body color

time between reproductive events

time between reproductive events

Step-by-step explanation

At condition of mutation selection equilibrium, heritability of reproductive traits are very low. Higher heritability means trait evolve faster, fewer generations are required for the trait to increase to the same degree as a trait with lower heritability.

Mutation-selection balance is an equilibrium in the number of deleterious alleles in a population that occurs when the rate at which deleterious alleles are created by mutation equals the rate at which deleterious alleles are eliminated by selection.
