1910 Bot. Gaz. 49 114 The occurrence of these two different types of hermaphrodite individuals harmonizes well with many experiences met with in other studies in heredity, which have led Johannsen..to distinguish between genotypes and phenotypes. These four hermaphrodite individuals, A, B, C, and D, belong to a single phenotype, but to two genotypes.

1911 W. Johannsen in Amer. Naturalist 45 134 All ‘types’ of organisms, distinguishable by direct inspection or only by finer methods of measuring or description may be characterized as ‘phenotypes’.

1931 S. J. Holmes Life & Evol. xiv. 277 A study of our checkerboard indicates that there are four phaenotypes.

1958 Antiquity 32 207 The Neolithic people were mostly of a different phenotype.

1971 D. J. Cove Genetics iv. 45 It is usual to refer to the genetic constitution of a strain as its genotype, and to its appearance as its phenotype.

1995 Boston Bk. Rev. Apr. 6/2 Heritability..is a measure of the extent to which genotype (the genetic basis of a trait) matches phenotype (the actual expression of that trait) in a given population.

1959 Lancet 26 Dec. 1189/2 I have therefore analysed the body build of those sons who had been phenotyped—unfortunately not all.

1990 Internat. Immunol. 2 1025/2 We phenotyped adult thymocytes bound to or detached from epithelial monolayers after different incubation times at 37°C.

2002 Mutation Res. 506 205 A subgroup of 349 cases and 467 controls was phenotyped for CYP1A2 by a caffeine test.
