Brit.

/ˈɑktəˌplɔɪd/

Forms: 1900s– octaploid, 1900s– octoploid.

Origin: Formed within English, by compounding. Etymons: octo- comb. form, -ploid comb. form.

Etymology: < octo- comb. form + -ploid comb. form. Compare earlier diploid adj.On the form in octa- see discussion s.v. octo- comb. form.

Biology.

A. adj.

Containing eight homologous sets of chromosomes (i.e. four times the diploid complement); made up of somatic cells of this kind.

1921 Amer. Naturalist 55 268 The chromosome number in the root tips is in general constantly 20 (seldom does the number approach the octoploid number).

1923 Bot. Gaz. 76 217 The assumption that unknown parents, tetraploid, hexaploid, and octaploid..produced, by crossing with diploid forms in preglacial times, plants identical with the Caninae of today save for ‘embryo mutation’, appears highly speculative.

1961 Lancet 26 Aug. 488/1 The finding of 8 sex-chromatin bodies in an octaploid XXXY cell can be predicted from the above formula.

1974 Sci. Amer. Aug. 73/2 If a hexaploid wheat (T. aestivum) is crossed with rye, the result is an octoploid triticale.

1988 Zool. Jrnl. Linn. Soc. 94 2 Polyploidy in anurans is rare, yet there are diploid, tetraploid, octoploid and dodecaploid species of Xenopus.

B. n.

An octoploid individual, type, or species.
