 Johannsen raised another concern about genes as particulate factors when he asserted that the traits “of the organism in toto are the results of the reactions of the genotypical constitution” (1911: 147; his emphasis); there was no “suggestive value” in the idea that “discrete particles of the chromosomes are ‘bearers’ of special parts of the whole inheritance in question” (1911: 131–2). Yet Mendel’s original experiments could be seen to support that very idea: the traits of the peas were not only dichotomous, but there was no pattern of co-occurrence of variants of the different traits, as would be the case if, say, crinkly peas occurred more often on dwarf plants. Given such independent assortment of traits, it would make sense, contra Johannsen, to talk of a pair of factors or genes for crinkly peas. A new transmission conception of heredity was plausible.
