The name Zygomycota refers to the zygosporangia characteristically formed by the members of this clade, in which resistant spherical spores are formed during sexual reproduction. Zygos is Greek for "joining" or "a yoke", referring to the fusion of two hyphal strands which produces these spores, and -mycota is a suffix referring to a division of ...
The Zoopagomycotina are a subdivision (incertae sedis) of the fungal division Zygomycota sensu lato. [1] It contains 5 families and 20 genera. [2] Relationships among and within subphyla of Zygomycota are poorly understood, and their monophyly remains in question, so they are sometimes referred to by the informal name zygomycetes.
The study of reproduction and development in organisms was carried out by many botanists and zoologists.. Wilhelm Hofmeister demonstrated that alternation of generations is a feature that unites plants, and published this result in 1851 (see plant sexuality).
[2] [8] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea. However, some processes in bacteria, including bacterial conjugation, transformation and transduction, may be considered analogous to sexual reproduction in that they incorporate new genetic information.

Most male fish have two testes of similar size. In the case of sharks, the testes on the right side is usually larger [citation needed].The primitive jawless fish have only a single testis, located in the midline of the body, although even this forms from the fusion of paired structures in the embryo.

Fungal fossils do not become common and uncontroversial until the early Devonian (416–359.2 Ma), when they are abundant in the Rhynie chert, mostly as Zygomycota and Chytridiomycota. [ 2 ] [ 23 ] [ 24 ] At about this same time, approximately 400 Ma, the Ascomycota and Basidiomycota diverged, [ 25 ] and all modern classes of fungi were present ...
