allotetraploidn.adj.

1930 W. J. C. Lawrence in Genetica 12 272 Hybrid tetraploid (allo-tetraploid).

1957 M. Abercrombie et al. Dict. Biol. 14 An ordinary hybrid is usually sterile because its chromosomes cannot pair during meiosis. But if it becomes an allotetraploid it solves this difficulty because each chromosome then has a homologue with which it can pair.

1989 Jrnl. Heredity 80 70/1 These and our previous findings indicate that téf is an allotetraploid or an effectively diploidized autotetraploid.

2005 C. R. Clement in G. Prance & M. Nesbitt Cultural Hist. Plants vi. 87 The sour cherry is an allotetraploid between the sweet cherry and the ground cherry.

1932 Bot. Gaz. 94 398 In all these plants only two chromosome of each distinguishable shape were present.., which very strongly suggests that they are of an allotetraploid origin similar to that of Primula kewensis.

1970 T. G. Dobzhansky Genetics Evol. Process xi. 386 Genome B may have been derived from a species of the grass Agropyron; an allotetraploid hybrid of this with T[riticum]aegilopoides (a relative of the neolithic cultivated T. monococcum) gave the tetraploid T. dicoccoides, the ancestor of the modern hard wheat, T. durum.

2002 Jrnl. Heredity 93 364/2 All three monosomes were found in the D subgenome of allotetraploid cotton and were not linked to the N₁ or n₂ alleles.
