Question

Which is an example of selective breeding

Answer 1

"Dogs are selectively bred for temperament and a variety of appearance traits (coat type, color, size). Some of this has to do with breeding dogs for certain jobs (hunters, herders, protectors etc) but a lot of it is just a matter of companionship.

Cows have also been selectively bred. Angus cows are bred to increase muscle mass so that we can get more meat out of them, dairy cows are bred for increased milk production."
