Two populations of the highly ornamented white-crested sparrow species are spatially separated by a mountain range.Males from the two populations exhibit differing elaborate courtship displays.When a female appears,the males from the eastern population approach the female while bobbing their heads and spreading their wings,while the western population approaches a female by hopping and flapping their wings.Individuals from each population reared in isolation exhibited the same courtship displays as those in the wild.
-After mating a female from the eastern population to a male from the western population,the resulting male offspring exhibited a hybrid courtship display,bobbing their heads and flapping their wings.This indicates that
A)courtship displays are a result of environmental pressures.
B)the elicited courtship display depends on female response.
C)courtship displays are under the control of more than one gene.
