Which of the following statements about plant height heritability is CORRECT?

A) In plant height experiments, estimates of heritability under the same light/humidity conditions will be the same regardless of the genotypes of parents.
B) In plant height experiments, estimates of heritability under the same light conditions will be the same regardless of the humidity values.
C) Heritability values will become larger as the plants themselves get older.
D) Estimates of plant height heritability may vary under different growing conditions, including changes in light/humidity.
E) A difference in heritability between two plant populations indicates that genetic factors only influence plant height in one of the populations.
