What is Sexual Reproduction in fungi?5 answersSexual reproduction in fungi involves the exchange and recombination of genetic material, leading to increased genetic diversity. It is a common phenomenon observed in many fungal species. Fungi can reproduce sexually through two different modes: heterothallism and homothallism. Heterothallism requires two compatible mating types to undergo mating, while homothallism allows the organism to be self-fertile. The process of sexual reproduction and sex determination is governed by the mating type (MAT) locus, which contains genes involved in sexual reproduction. The MAT locus can vary in structure and composition among different fungal species. Sexual reproduction in fungi is important for repairing DNA damage and increasing genetic variation, which can enhance the adaptability and survival of fungal populations.
