1911 Amer. Naturalist 45 26 Thus it is of the greatest importance that the living material shall be shown to be either simple genotypes or that its phaenotypic nature be apprehended in order that the integration and combination of these forms shall not be mistaken for environic effects.

1935 H. S. Jennings Genetics viii. 186 The same phaenotypic character..may be due in different cases to the alteration of diverse genes.

1970 Sci. Amer. Feb. 62/3 It seems likely that the highlanders have derived their special qualities from acclimatization—in short, that their response to their environment is phenotypic rather than genotypic.

1993 K. S. Robinson Green Mars (new ed.) 166 Intense UV radiation would break a number of genes, but if they were replicated in the other sets of chromosomes, then there was likely to be no phenotypic display of the damage, and no impediment to reproduction.

1923 Proc. Royal Soc. B. 95 231 Slowly it came to be recognized that this phenotypic selection resulted in the production of a deformed and still-born calf.

1958 Amer. Naturalist 92 315 Heterozygotes developing at a temperature A of 26°C are indistinguishable from homozygous wildtype flies... Phenotypic selection which at 26°C is not possible, becomes feasible at 14°C.

2003 Crop Sci. (Nexis) 1 May 755 Recurrent phenotypic selection has also been used as a breeding method for increasing rust resistance for other perennial grasses.
