キイロタマホコリカビ
Members of the Mycetozoa group are able to undergo sexual reproduction either by heterothallic or homothallic mating. An analysis of meiosis-related genes in the "Dictyostelium discoideum" genome revealed that 36 of the 44 genes tested were present in the genome. One gene, "Spo11", was absent in the Mycetozoa, raising questions about the assumed universal role of "Spo11" as an initiator of meiosis.
