Final answer:
Yes, a population of pure-breeding lightly spotted brown pigs can be created through selective breeding of individuals with the desired traits, as pig coat patterns are genetically determined.
Step-by-step explanation:
It is possible to establish a pure-breeding population of lightly spotted brown pigs through selective breeding. This would involve continuously breeding pigs that exhibit the desired coat pattern until you consistently obtain offspring with those same physical traits.
This process relies on the fact that coat color and patterns are heritable traits in pigs, controlled by their genetic makeup.
Option A, which suggests that lightly spotted individuals could be selectively bred to achieve a pure-breeding population, is the correct answer. This is how breeders develop and maintain distinct animal breeds with specific physical characteristics. Coat patterns and colors in pigs are indeed genetically determined, therefore this principle can be applied to achieve the desired result in pig populations.
