Isogamy

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] Instead, organisms undergoing isogamy are said to have different mating types, most commonly noted as "+" and "−" strains.^[3]
