The answer is b. false.
Selective breeding is
used for animal or plant breeding to develop wanted phenotypes. By combining traits from two different breeds of one species, intentionally are reproducer organisms with desirable
traits. It could not occur between two different species. New species are produced by speciation and they are reproductive isolated from other species. Imagine what would happen if scientist could be able to combine traits from two different species, such as apple and mosquito.
