[1871C. R. Darwin Descent of Man viii. 282 (heading) Inheritance as limited by sex. Ibid. 285 If any variation appeared in a female pigeon, which was from the first sexually limited in its development to the females, it would be easy to make a breed with the females alone thus characterized. 1905Brit. Med. Jrnl. 28 Oct. 1094/1 The abnormality, though affecting both boys and girls, is mainly limited to one sex in each family.] 1923Jrnl. Genetics XIII. 215 As a contribution towards the adoption..of uniform terminology for the various modes of inheritance (at present, such terms as ‘sex-limited’ and ‘sex-linked’ are often used at random), I would point out that the denomination ‘sex-linked’ (geschlechtsgebunden) ought to be applied only to conditions of inheritance explainable by the presence of the factor in question in those sex-chromosomes which are normally found in individuals of both sexes. Ibid. 216 The expression ‘sex⁓limited inheritance’ is not very judicious... ‘Sex-limited manifestation’ would be better. 1944Genetics XXIX. 520 The mutant is strongly sex-limited in phenotypic expression. 1975Jrnl.
