The State University of New York states that animals reproduce by several sexual and asexual methods, with sexual reproduction, defined as the production of gametes with half of each parent's DNA and their union into diploid organisms, predominating. Sexual reproduction can be done externally, with eggs and sperm united outside an organism, or internally. Asexual reproduction takes a large number of forms, which vary between taxonomic groups.
