… A group of biological species bred and bred in a laboratory for research purposes is also called a population, but to clearly distinguish it from natural populations, it is often called an experimental population. In genetics, the word population is often used, and in particular, multiple populations with the same genetic source are called Mendelian populations or gamodemes. Conceptually, we can recognize several regional populations that show continuous or discontinuous physiological and ecological characteristics as the geographic distribution of each biological species expands, and subspecies populations that have already progressed to the point of being considered subspecies, and we can even imagine a species population that includes them. … *Some of the terminology that mentions "gamodeme" is listed below.

… 実験室において研究のために飼育増殖される生物種の一群もやはり個体群と呼ばれるが,自然の個体群と明確に区別するため,実験個体群と呼ばれることが多い。遺伝学では集団という語を用いる場合が多く,特に同じ遺伝子給源をもつ複数の集団をメンデル集団またはガモデームgamodemeと呼んでいる。概念的には,それぞれの生物種の地理的分布の広がりにつれて連続または不連続的な生理・生態的特性を示すいくつかの地域個体群や,すでに亜種とされるほどの種分化の進んでいる亜種個体群などを認めることができるし,さらにはそれらを包含した種個体群というものを想定することもできる。… ※「gamodeme」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 |
