c. : the process by which plants and animals give rise to offspring that fundamentally consists of the segregation of a portion of the parental body and its subsequent growth and differentiation into a new individual, that in its simpler forms is asexual or vegetative and involves the multiplication of a single parent by building, fission, or the formation of specialized bodies (as tubers, corms, or gemmules) any of which normally grows and differentiates into a new living unit genetically identical with the parent, that may also be sexual involving union of gametes of two parents in fertilization to form a new individual combining genetic characters from each parent although in various modifications offspring may be produced by a single parent in an essentially sexual manner, and that among the higher plants and in many invertebrate animals is characterized by sexual generations alternating with asexual in a characteristic pattern so that long-continued vegetative reproduction without genetic recombination is the exception rather than the rule — compare clone, hermaphrodite, parthenogenesis
