karyogramn.

/ˈkarɪəʊɡram/

Etymology: < karyo- comb. form + -gram comb. form.

Biology.

a. A karyotype or idiogram. In quot. 1952 (by a Japanese writer) perhaps an error for karyotype, which is used throughout the paper (in sense karyotype n. 1a).

1971 Nature 9 Apr. 368/1 (caption) A typical karyogram of Chinese hamster strain wg 3 IMP-: twenty-two chromosomes, all but one (bottom right) distinguishable from those of mouse strain 3T3 TK-.

b. A diagram in which each chromosome of a set is represented by a point positioned with respect to a vertical and a horizontal axis, these axes corresponding to two numerical characteristics of the chromosomes.

1960 K. Patau in Amer. Jrnl. Human Genetics XII. 255 A chromosome characterized by two quantities is best represented by a point in a two-dimensional co-ordinate system. The choice of these quantities—total length and arm index or two arm lengths, is in principle irrelevant... Let the percent length, l, of the longer arm serve as abscissa and the percent length, s, of the shorter arm as ordinate. The scatter diagram obtained by plotting in this manner all chromosomes of the given complement will henceforth be referred to as a ‘karyogram’.

1966 Stewart & Killean in Darlington & Lewis Chromosomes Today I. 211 In the production of karyograms the basic data are taken from a photographic enlargement of the chromosome plate to be analysed.

1969 Nature 22 Nov. 801/2 The results of a chromosome analysis can be displayed in several ways. The methods commonly used are the karyotype..and the karyogram, in which each chromosome is represented by a point in a bivariate coordinate system.
