1917 P. B. Sears in Ohio Jrnl. Sci. 17 98 The fact that the embryo arises from an unfertilized egg-cell of unreduced chromosome count makes it seem advisable to employ the expression ‘amiotic parthenogenesis’—to describe the phenomenon, rather than the term ‘apogamy’.

1945 M. J. D. White Animal Cytol. & Evol. xiii. 283 Ameiotic parthenogenesis is genetically equivalent to clonal or vegetative reproduction.

1979 Amer. Zoologist 19 699/1 A major consequence of ameiotic asexual reproduction is the creation of many organisms in a population, each bearing the same genotype.

2001 J. G. Nagaraju et al. in E. C. R. Reeve Encycl. Genetics 220/2 No natural ameiotic parthenogenesis has yet been demonstrated [in Bombyx mori].
