Physics (ed. 12) i. iii. 49 To convert a certain number of foot-pounds into kilogramme-metres we have..foot/metre = 0.3048, the unit factor being thus 0.1383. 1907 Science 15 Nov. 652/2 The bodily characters may result from the transmission of distinct unit-factors. 1911 W. Johannsen in Amer. Naturalist 45 132 I have proposed the terms ‘gene’ and ‘genotype’..to be used in the science of genetics. The ‘gene’ is nothing but a very applicable little word, easily combined with others, and hence it may be useful as an expression for the ‘unit-factors’, ‘elements’ or ‘allelomorphs’ in the gametes, demonstrated by modern Mendelian researches. 1966 E. A. Carlson Gene iv. 26 When unit-character was changed to ‘unit-factor’ or to ‘factor’ alone, Castle no longer dissociated the transmitting agent from its effect on a character. 1988 H. O. Daley Probl. in Chem. (ed. 2) i. 10 This is the unit factor that converts from pounds to grams. 2007 T. L. White et al. Forest Genetics iii. 37 Mendel further hypothesized that one unit factor (i.e. allele) is dominant to the other recessive factor. 2014 S. S. Zumdahl Chemistry (ed. 9) i. 22 The unit factor for the conversion of feet to inches must be cubed to accommodate the conversion of ft3 to in3. < as lemmas |
