1911 T. H. Morgan in Science 7 Apr. 537/1 (caption) D = Dominant. R = Recessive. RR = Neuropathic subject (nulliplex inheritance). DD = Normal subject of pure normal ancestry (duplex inheritance). DR = Normal subject with neuropathic taint from one parent (simplex inheritance).

1921 Amer. Naturalist 55 257 A Poinsettia plant may, to speak in terms of the dominant factor, be considered nulliplex with no dominant genes, or simplex, duplex or triplex with, respectively, 1, 2, or 3 dominant factors (i.e., usu., homozygous for the recessive allele).

1929 Jrnl. Genetics 21 141 From previous results it has been assumed that 14/26 is triplex for Y and heterozygous for I, and that ‘White Star’ is nulliplex for Y and heterozygous for I.

1963 K. R. Lewis & B. John Chromosome Marker iv. iii. 328 With chromatid segregation a triplex can produce nulliplex offspring.

1990 Amer. Jrnl. Bot. 77 Suppl. 75 In some examples the observed recessive phenotype (nulliplex genotype) numbers are significantly higher than expected.
