English term or phrase: deme
Definition from Hypermedia Glossary Of Genetic Terms:
A locally interbreeding population.

Example sentence(s):
  • Basically, the virtual world where migrations take place is constituted by a matrix of demes. Each deme has its own environmental characteristics according to the input files. Splatche
  • Key components of this simulation model include: (i) a three layer intra-deme population structure: hunter-gatherers, non-dairying farmers and dairying farmers. (ii) Population genetic simulation of a LP allele under selection, and an undrifted allele signifying general genetic background. (iii) Intra and inter-deme gene flow and sporadic longer distance migration (following a Gaussian random walk process). UNIVERSITY COLLEGE LONDON
  • The application of the island model is limited because it does not in fact contain explicit geography: migrants are equally likely to have come from any deme in the population. Oxford Journals

同类群,混交群体
Definition:
A subpopulation of a species: a discrete interbreeding group of organisms, with recognizable cytological or genetic characters, that is spatially distinct from other such groups, although it may be adjacent to them. Compare subspecies.
混交群体(同类群):一个不连续的异体交配的生物体类群。它们所具有的细胞学和遗传学上的性状在空间上与其他的类群不同,尽管它们可能是相邻的。

同类群,混交群体


Definition from EDU:
A subpopulation of a species: a discrete interbreeding group of organisms, with recognizable cytological or genetic characters, that is spatially distinct from other such groups, although it may be adjacent to them. Compare subspecies.

Example sentence(s):
  • 以家蝇为例,就是小到一个城市范围内,对家蝇来说环境条件仍不相同,例如厕所周围、垃圾周围、腐肉周围等等,具体生存条件也都不一致,因此种群内也可以分成小群或亚群,这种小群又称为同类群(deme),同类群的个体之间比较相似,因为在遗传性状上个体之间更为接近,且所处的环境条件相同。这些同一种内处于不同生境的种群或小的生态群就是新种形成的基础。例如分布于美洲落矶山脉的一种小鼠(Peromyscus maniculatus),根据生活在不同地域可分为四个亚种。它们的分布有互相重叠的区域,在这个区域中混居的亚种之间可以互相交配产生后代。 - 烟台大学  
  • 在更高的层次水平上,以整个繁殖群为选择单位,使得具有不同类型的基因型的群组在不同程度上消亡,称之为同生群(deme)间的选择。 - 虚拟科学院  
  • 赖特从1914年就开始研究豚鼠的肤色遗传及近亲繁殖效应。这项研究使他认识到“有效繁殖种群”(后来称为同类群或混交类群,demes)即使在野生动物中(这种群)一般也较小,使得采样误差成为不可忽略因素。 - 生物学思想发展史
