No, but you can work at one. You may purchase from a selection of shops in your town.
Humans have countered natural selection through hybrid breeding. Even crossing a male donkey with a female horse produces a mule. Crossing certain corn strains with other corn strains to produce more grain per ear.
because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding

The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
