A haploid set of chromosomes; the sum-total of the genes in such a set.
1930Cytologia I. 14 Chromosomes from different sets (or genoms) of Triticum vulgare show affinity toward each other. 1930[see allopolyploidy]. 1932Proc. 6th Int. Congr. Genetics I. 275 The inviability of deficient genomes in the haploid generation serves to some extent as an alternative distinction between mutation and deficiency. Ibid. II. 5 There are two species having genoms resembling C. neglecta. 1952C. P. Blacker Eugenics x. 243 The appearance of such terms as gene-complex and genome (denoting a set of chromosomes as a working unity) testify to the movement towards holism in genetics. 1965A. M. Srb et al. Gen. Genetics (ed. 2) vii. 190 Among organisms with chromosomes, each species has a characteristic set of genes, or genome. In diploids a genome is found in each normal gamete. It consists of a full set of the different kinds of chromosomes. 1970Sci. Amer. Oct. 19/1 The human genome..consists of perhaps as many as 10 million genes. |
