Question

Even if a trait has a high selection differential, it will not evolve if h2 = 0.
True or Fasle

Answer 1

Answer: True.

Explanation: h² is a factor that describes the heritability - the proportion of a trait that is encoded by genetic factors. If h² = 0, the variability in this trait cannot be inherited, therefore, cannot be transferred to offspring. And, thus, this trait cannot evolve.
