1931 B. Němec in Rep. Proc. 5th Internat. Bot. Congr. 1930 233 Many plants contain under normal conditions both diploid and polyploid cells. It is easy to get experimentally plants containing a varying number of polyploid cells. The author designates such plants mixoploid.

1931 B. Němec in Rep. Proc. 5th Internat. Bot. Congr. 1930 233 Mixoploid organs tend to eliminate the polyploid cells when they form a minority, especially when they are highly polyploid.

1944 Jrnl. Heredity 35 361/1 Individual anthers were mixoploid.

1967 Current Sci. 36 307 (heading) Preferential elimination of diploid cells in a colchicine-induced mixoploid tissue.

1990 Jrnl. Exper. Bot. 41 843/1 One further root..was shown to be mixoploid.

1939 Hereditas 25 111 As a result of the agar treatment entire plants occasionally become mixoploids.

1951 Nature 2 June 891/1 In many species the diploid tissue grows at the expense of the tetraploid, and such a mixoploid reverts rapidly to the diploid condition.

1971 J. Hamerton Human Cytogenetics I. vii. 224 Autosomal mosaics are less common, and about 1% of Down's syndrome patients are estimated to be mixoploids.

1996 Theoret. & Appl. Genetics 93 1234/1 A wide range of chromosome numbers were observed among the regenerated plants, including some apparent mixoploids.
