Question

1. the labradoodle is a breed of dog created when a labrador retriever is crossed with a poodle. the breeder who created the labradoodle thought that the combination of the gentle nature of the labrador retriever with the low shedding coat of the poodle would make it a good breed for people with allergies. the creation of the labradoodle is an example of — genetic drift, since different dog breeds are capable of randomly mating genetic mutation, since a new type of dog was created during the breeding gene flow, since traits from one population are being mixed with a different population natural selection, since mixed breeds are more likely to survive than pure breeds

Explanation:

• Genetic drift refers to random changes in allele frequencies, which does not apply here as this is intentional breeding, not random mating.
• Genetic mutation is a change in DNA sequence, not the intentional mixing of traits from two established breeds.
• Gene flow involves the transfer of genetic traits between different populations, which matches the intentional crossbreeding of Labrador Retrievers (one population) and Poodles (another population) to combine their traits.
• Natural selection is driven by environmental survival pressures, while this is artificial, human-directed breeding, not natural survival-based selection.

Answer:

C. gene flow, since traits from one population are being mixed with a different population
