Identical twins result from the fertilization of a single egg cell by a single sperm that divides into two embryos. The embryos will have the same genetic material and will be identical in appearance. Fraternal twins result from the fertilization of two separate egg cells by two separate sperm. Multiples and multiparous refer to pregnancies that result in the birth of more than one baby, but do not specify how the fertilization occurred.
