Question

Mention the steps involved in the sexual reproduction of Rhizopus.

Answer 1

Sexual reproduction is present and takes place through gametangial copulation.
2. Most of the species are heterothallic but Rhizopus sexualis is homothallic.
3. There is no morphological distinction between the two sexual hyphae although physiologically they are dissimilar.
4. Since physiologically dissimilar thalli (hyphae) are involved in sexual reproduction, this phenomenon is called heterothallism.
5. Mycelia which produce gametangia are of opposite strains (+) or (-).
