Artificial selection has played a significant role in shaping the evolution of various organisms. We can see its effects in the diverse breeds of dogs that exist today, which have been selectively bred by humans for specific traits. Consider the implications of this process on the genetic diversity of these dog breeds. Based on your understanding of artificial selection and its role in evolution, why might too much selective breeding pose a potential risk to the genetic health of a dog breed?

Excessive selective breeding can make dog breeds more adaptable to environmental changes due to the concentration of specific traits.

Selective breeding always leads to healthier and stronger dog breeds due to the enhancement of desirable traits.

Too much selective breeding can lead to decreased genetic diversity and increased risk of harmful genetic conditions in dog breeds.

Too much selective breeding has no significant impact on the genetic health of a dog breed.

Selective breeding increases genetic diversity and reduces the risk of harmful genetic conditions in dog breeds.
