A scientist measured heritability in yield per acre of a strain of wheat grown on a farm in eastern Europe and determined that it was 80%. She can therefore conclude that:
A)80% of variation among individuals when the same strain of wheat is grown in Nebraska will be due to genetic differences.
B)80% of variation among individuals when the same strain of wheat is grown on the same farm in eastern Europe the following year will be due to genetic differences.
C)when the same strain of wheat is grown on two different farms at the same time, 80% of the average difference in yield per acre will be due to genetic differences among populations.
D)80% of the total yield is due to genotype and 20% to environment.
E)None of the answer options is correct.

Question

Quizplus · Accepted Answer

Heritability estimates are specific to the population and environment in which they were measured. They do not necessarily apply to different environments, times, or explain the proportion of yield due to genetics versus environment in a direct way.
