farmers selectivly breed cattle to get the characteristics they desire for the job they are going to put the offspring to do
Hundreds and hundreds of years. It's still happening today, actually.
All cows that exist today have been selectively bred to be what they are now. They also will be selectively bred to produce the desired calf that the farmer needs to either produce more calves or be slaughtered for beef production later in its life.
Penguins breed with other penguins of the same species.
Farmers don't usually breed honey bees, but they do need them for pollination purposes depending on the type of farm. For example, a livestock farmer doesn't need bees but a fruit farmer definitely does need bees.

Pure breeding is the process of selectively breeding animals to produce some desired, different, animal.
Genetics is the difference between the pink silkworm cocoon or the white cocoon. Silkworms in the wild spun yellow silk to blend into the dead foliage. Today silkworm farmers are beginning to selectively breed for different colors.
