Which of the following statements is supported by this observation? A) Natural selection had not occurred very frequently in the wild dog populations. B) There was enough heritable variation in the wild canine species to create a variety of features. C) Heritable variation is low; otherwise the there would be more wild dog species.Heritability is one important component of the equation used to predict genetic progress from selection to improve a trait. For the simplest form of selection called “mass selection” or selection on phenotypes measured on individuals in a population, that equation is: ΔG = ih2σp E4.

Natural selection is based on all of the following except. individuals who survive longer tend to have more offspring than those who die young. genetic variation exists within populations. Individuals adapt to their environments and, thereby, evolve. populations tend to produce more offspring than the environment can support.
