History

Etymology

From Ancient Greek μείωσις (meíōsis, “a lessening”), from μειόω (meióō, “I lessen”), from μείων (meíōn, “less”). The biological sense was coined by British biologists John Bretland Farmer and John Edmund Sharrock Moore in 1905 as maiosis in a paper in the Quarterly Journal of Microscopic Science, with the spelling corrected on etymological grounds later that year. Doublet of miosis.
