1958 C. P. Swanson Cytol. & Cytogenetics ix. 300 This gradual change..will give both tissues of mixed ploidy and cells with an uneven degree of polyteny in the individual chromosomes. Mickey..has also shown this type of mixoploidy to be true for the spermatogonia in the testes of the grasshopper, Romalea.
1963 A. Levan & A. Müntzing in Portugaliae Acta Biol. A. 7 11 The present writers would suggest that the term mixoploidy should include all cases in which cell populations contain more than one chromosome number irrespective of whether the numbers are euploid or aneuploid.
1971 J. Hamerton Human Cytogenetics I. vii. 225 In vitro studies on mixoploidy should include the use of single cell clones from a mixoploid culture so that the only genetic difference is confined to a single chromosome.
1993 Human Reproduction 8 895/1 Mixoploidy seems to be a normal feature in preimplantation embryos.
