"The "Vicar of Bray" hypothesis (or Fisher-Muller Model ) attempts to explain why sexual reproduction might have advantages over asexual reproduction. Reproduction is the process by which organisms give rise to offspring. Asexual reproduction involves a single parent and results in offspring that are genetically identical to each other and to the parent. In contrast to asexual reproduction, sexual reproduction involves two parents. Both the parents p… " - Fisher-muller hypothesis
