Question

suppose that the natural ranges of horses and donkeys were to overlap.which of the following statements best describes what would likely happen to the populations over time?
select one:
a) The hybrid offspring( mules) would become widespread and mate with members of both populations.
b) The hybrid offspring would mate with other hybrid offspring to produce viable offspring
c) The hybrid offspring would be less reproductive fit and reinforcement could strengthen postzygotic barriers
d) eventually all members of both populations would be hybrids
e) the hybrid offspring would be less reproductive fit and reinforcement could strengthen prezygotic barriers

Explanation / Answer

Ans.)e- the hybrid offspring would be less reproductive fit and reinforcement could strengthen prezygotic barriers

Reason-mules are comparatively infertile offspring

They are reproductive unfit and after few crossing may develop adaptive changes to decrease mule-mule crossing.

They might be able to reproduce efficiently by pure breed, though
