You Are Studying a Highly Inbred Strain of Barley

Multiple Choice

You are studying a highly inbred strain of barley.After many generations of inbreeding,you now assume that the genetic variation is zero.Suppose that you raise many individuals of your barley strain in a field in southeastern Michigan and then measure their height after one month of growth.You find that the variance in their height is 4.0.The broad-sense heritability of this trait is 0.From this particular study you can conclude that:

A) genetics does not play a major role in determining the height of barley plants.
B) if you were to repeat the same experiment in Iowa,you would obtain a different broad-sense heritability.
C) if you were to repeat the same experiment in Iowa,you would obtain the same broad-sense heritability.
D) in barley plants,height is not inheritable.
E) the line of barley plants that you are studying is not inbred enough.
