1935 Philos. Trans. (Royal Soc.) B. 225 247 This cell can only have arisen from a duplication (i.e., autotetraploidy), probably in the last premeiotic telophase, of the 15 chromosomes normal to the plant.
1942 J. S. Huxley Evolution iii. 87 The normal diploid complement of chromosomes of a species may become doubled (autotetraploidy).
2007 H. Muller et al. in C. d'Enfert & B. Hube Candida 81 This pattern could result from a single complete duplication of an ancestral genome (autotetraploidy) or from the fusion of two related species (allotetraploidy).
