Asexual reproduction results from mitotic cell division (mitosis). During asexual reproduction, one cell, called the parent cell, divides into two identical daughter cells. The new organisms, called offspring, are genetically identical to the parent cell.There is no fusing (joining) of cells in this type of reproduction.Asexual reproduction is more common in invertebrate animals than in vertebrate animals. Unicellular and multicellular plants can reproduce both asexually and sexually.inary fission is the simplest type of asexual reproduction. During binary fission, a one.celled organism divides by mitosis to form two daughter cells of equal size. Both the nucleus and the cytoplasm divide equally. The chromosomes of the offspring are identical to that of the parent.
