After several generations of artificial selective breeding, a plateau is reached where artificial selection is no longer effective. This is called the ________.
A) realized limit
B) realized heritability
C) selection coefficient
D) selection limit

Question

Quizplus · Accepted Answer

The selection limit is the point in artificial selective breeding where further selection no longer results in significant improvement. This is because the genetic variation has been reduced to the point where there are no more desirable traits to select for. The other options are not accurate descriptions of this phenomenon. Realized heritability refers to how much of the observed variation in a trait is due to genetic factors, while the selection coefficient is a measure of how much a particular trait affects an organism's fitness. The realized limit is not a term used in this context.
