Front

What is one major drawback of selective breeding?

Back

Front

How does selective breeding affect gene variety?

Back

Selective breeding can reduce gene variety because it often involves breeding individuals with similar traits, which can limit the gene pool.

Front

What is a potential health issue associated with selective breeding?

Back

A potential health issue associated with selective breeding is that it can lead to inherited health problems in the offspring.

Front

What evidence supports the idea that all dog breeds descended from wolves?

Back

Evidence shows that the wolf is the ancestor to all breeds of dogs, and this variation arose through selective breeding.

Front

What is the relationship between selective breeding and evolution?

Front

What are some common traits selected for in dogs through selective breeding?

Back

Common traits selected for in dogs include size, coat color, temperament, and specific abilities (e.g., herding, hunting).
