Question

Quizplus · Accepted Answer

In social groups with mate guarding, there is a relatively high occurrence of extrapair copulations, which result in a percentage of offspring. This is why mate guarding is thought to have evolved as a means to increase the certainty of paternity. Genetic testing has confirmed that extrapair copulations do occur and that they can result in offspring outside of the primary social unit. A and B are not necessarily true in all cases of mate guarding, and D is not necessarily true for all instances of extrapair copulation.
