Isogamy - Wikipedia
网页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 ]
Difference Between Anisogamy Isogamy and Oogamy

网页2016年10月10日 · Here, we review isogamy, some of its essential features, outline where it can be found, and the many fascinating ways in which life in the isogamous world differs from our ‘norm’. Our story begins with the last common ancestor of all eukaryotes.
Isogamy - an overview | ScienceDirect Topics
网页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).

Evolutionary trajectories explain the diversified evolution of isogamy ...
网页2012年8月8日 · 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., …
