Isogamy is a form of sexual reproduction that involves gametes of the same morphology (indistinguishable in shape and size), found in most unicellular eukaryotes. Because both gametes look alike, they generally cannot be classified as male or female. Instead, organisms undergoing isogamy are said … See more The literal meaning of isogamy is "equal marriage" which refers to equal contribution of resources by both gametes to a zygote. The term isogamous was first used in the year 1887. See more Almost all unicellular eukaryotes are isogamous. Among multicellular organisms, isogamy is restricted to fungi such as See more Biology • Anisogamy • Evolution of sexual reproduction See more Isogamous species often have two mating types. Some isogamous species have more than two mating types, but the number is usually … See more It is generally accepted that isogamy is an ancestral state for anisogamy and that isogamy was the first stage in the evolution of sexual reproduction. Isogamous reproduction evolved independently in several lineages of plants and animals to See more WebIn Spirogyra all the cells of the filament can form the gametes, which are morphologically similar and are referred to as isogametes. This phenomena of sexual reproduction is known as isogamous type of sexual reproduction. But at the time of conjugation one of the two isogametes shows motility and is considered as the male gamete.
