allelomorphn.

1902 W. Bateson Mendel's Princ. Heredity i. 27 We know that the several unit-characters are of such a nature that any one of them is capable of independently displacing or being displaced by one or more alternative characters taken singly, we may recognize this fact by naming such unit-characters allelomorphs.

1949 C. D. Darlington & K. Mather Elements of Genetics v. 114 In addition to such simple allelomorphs, however, particular loci in scores of species show whole series of alternatives, multiple allelomorphs as they are called.

1984 Systematic Bot. 9 450/2 Multiple allelomorphs at putative polymorphic loci are designated by lower case letters.

2003 L. Moss What Genes can't Do i. 27 His [sc. Bateson's] term ‘allelomorph’ for the units of transmission captures this sense of an encapsulated piece of organismic form.

1902 W. Bateson & E. R. Saunders in Rep. Evol. Com. Royal Soc. I. 142 It does not appear as yet that simple allelomorphism occurs between any two colours, of which neither is xanthic or albino.

1947 J. B. S. Haldane What is Life? xxxviii. 151 Cuénot discovered multiple allelomorphism and described a lethal gene in France in 1905.

2004 E. A. Carlson Mendel's Legacy 248 Sturtevant recognized that a normal gene could mutate to more than one state when he interpreted multiple allelomorphism.
