...Diploid species are represented by 2 x , tetraploid species by 4 x , and hexaploid species by 6 x . The karyotype corresponding to this basic number is called the basic karyotype, and its analysis is called basic karyotype analysis. This method can clarify the genome composition of a species, and is therefore considered to be a powerful means of elucidating the phylogenetic relationships between species and genera, as well as the state of phylogenetic differentiation. ... *Some of the terminology that refers to the "basic karyotype" is listed below.

…そして,二倍種は2x,四倍種は4x,六倍種は6xで表される。この基本数に相当する核型を特に基本核型と呼び,その核型分析を特に基本核型分析という。これによって種のゲノム構成を明らかにできるので,この分析法は種間および属間の系統分類学的な類縁関係ならびに系統分化の様相を解明する有力な一手段と考えられる。… ※「基本核型」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
