Living organisms have two types of reproduction. i.e. sexual and asexual reproduction. Asexual reproduction is a reproduction in which an offspring is obtained from a single parent. Genetic information in both the parent and the offspring are identical. So in asexual reproduction the parent and the offspring have identical genetic makeup.
