Isogamy is a form of sexual reproduction that involves gametes of the same morphology (indistinguishable in shape and size), and is found in most unicellular eukaryotes. [1] Because both gametes look alike, they generally cannot be classified as male or female . [ 2 ]

May 15, 2017 · The main difference between anisogamy isogamy and oogamy is that anisogamy is the fusion of gametes in dissimilar size while isogamy is the fusion of gametes in similar size and oogamy is the fusion of large, immotile female gametes with small, motile male gametes.

Isogamy occurs when all gametes are morphologically the same, especially in size (within the normal variation that exists in populations, i.e., they are not absolutely identical). It does not imply that all gametes are functionally equal because there are almost always different mating types (with disassortative fusion).

Gametes of animals, some algae and fungi, and all higher plants exhibit an advanced form of heterogamy called oogamy. In oogamy one of the gametes is small and motile (the sperm), and the other is large and nonmotile (the egg). The Editors of Encyclopaedia Britannica This article was most recently revised and updated by Joan Lackowski.

Isogamy is a reproductive system where all gametes are morphologically similar, especially in terms of size. Its importance goes beyond specific cases: to this day non-anisogamous systems are common outside of multicellular animals and plants, they ...

Three evolutionary trajectories are possible: (i) large isogamy (to 5, 5), (ii) smaller isogamy (to 9, 9), and (iii) anisogamy (by 7, 4 to 9, 4). The first evolutionary trajectory, isogamy with larger gametes, leads to evolutionary stability (i.e., an ESS but not CSS).

Jun 27, 2018 · isogamy (īsŏg´əmē), in biology, a condition in which the sexual cells, or gametes, are of the same form and size and are usually indistinguishable from each other. Many algae [1] and some fungi [2] have isogamous gametes.

Conjugation between two equal gametes or two individual cells alike in all respects. Farlex Partner Medical Dictionary © Farlex 2012. n. Reproduction by the fusion or conjugation of isogametes, …

Sexual reproduction between two cells that does not involve gametes (e.g. conjugation between two mycelia in basidiomycete fungi), is often called isogamy, although it is not technically isogametic reproduction in the strict sense.
