网络扩展资料
Heterothallism（异配生）is a biological term used to describe a type of sexual reproduction in fungi where two distinct mating types are required to produce offspring. In heterothallic fungi, there are two different types of mycelia that each contain one of the two mating types.
The term is derived from the Greek words "heteros" (meaning "different") and "thallos" (meaning "young shoot" or "twig").

Usage
Heterothallism is a technical term used specifically in the field of mycology (the study of fungi). It is not commonly used in everyday language.
Explanation
In heterothallic fungi, there are two different types of mycelia: one contains the " " mating type and the other contains the "-" mating type. To reproduce, the mycelia of opposite mating types must come into contact with each other and fuse, forming a structure called a "dikaryon." The dikaryon then produces spores through a process called meiosis, which can be dispersed and germinate to form new mycelia.
Synonyms
Heterothallism does not have any direct synonyms, as it is a specific term used in the field of mycology.
Antonyms
Autotallism (自配生) is the opposite of heterothallism, where a single organism can mate with itself to produce offspring.
