By the early 1970s, "genome size" was in common usage with its present definition, probably as a result of its inclusion in Susumu Ohno's influential book Evolution by Gene Duplication, published in 1970.
1970ndate alguseks oli ″genoomi suurus″ üldiselt kasutusel selle praeguses tähenduses, mille põhjuseks peetakse Susumu Ohno mõjuka raamatu „Evolution by Gene Duplication“ ilmumist 1970. aastal.
