The scatterplots show the relation between the average phenotype of parents (x-axis) and that of their offspring (y-axis) for two traits in a variety of tropical sweet corn. One trait is ear height, which has a heritability of 75%; and the other is ear length, which has a heritability of 25%. To make the axes comparable, for each trait the phenotypic measurement is expressed as a deviation from the overall mean in multiples of the standard deviation. Which of the following matchups is CORRECT?
A)Ear length is trait K and ear height is trait Q.
B)Ear length is trait Q and ear height is trait K.
C)Ear length and ear height are both trait K.
D)Ear length and ear height are both trait Q.
