Detailed explanation-1: -Sexual reproduction is a rich source of genetic variation and commonly observed among fungi. Basically two different modes of sexual reproduction are observed in fungi, namely heterothallism where two compatible mating types are required to undergo mating and homothallism in which the organism is self-fertile.

Detailed explanation-2: -In sexual reproduction, hyphae from two fungi grow together and eventually produce spores, which develop into fungi that differ from either parent.

Detailed explanation-3: -In fungi, sexual reproduction often occurs in response to adverse environmental conditions. Two mating types are produced. When both mating types are present in the same mycelium, it is called homothallic, or self-fertile. Heterothallic mycelia require two different, but compatible, mycelia to reproduce sexually.

Detailed explanation-4: -Fungi usually reproduce both sexually and asexually. The asexual cycle produces mitospores, and the sexual cycle produces meiospores. Even though both types of spores are produced by the same mycelium, they are very different in form and easily distinguished (see above Sporophores and spores).

Detailed explanation-5: -Ascospores & basidiospores are sexual spores. Ascospores, Basidiospores, zygospores and oospores are the examples of sexual spores. Sporangiospores, conidia, arthrospore, chlamydospore are the examples of asexual spores.
