Question

over years of selective breeding, french bulldogs have developed extremely short snouts and flat faces. these traits, although attractive to the dog owners, can make it difficult for the dogs to breathe. which of the following processes led to the presence of these traits? choose 1 answer: a environmental selection b natural selection c artificial selection d sexual selection

Explanation:

The problem is about the process that led to the traits in French bulldogs. Selective breeding by humans (dog owners) to get desired traits (short snouts, flat faces) is artificial selection. Environmental selection is about environment-driven changes, natural selection is nature-driven, and sexual selection is about mate choice. Here, human intervention (selective breeding) is key, so artificial selection (option C) is correct.

Answer:

C. Artificial selection
