单词 | hybrid swarm |
释义 | hybrid swarmhybrid swarm[′hī·brəd ′swȯrm]hybrid swarmhybrid swarma group of genetically variable organisms resulting from the hybridization of two previously distinct and separate populations. Subsequent crossing and backcrossing results in a very variable population as a result of segregation. Often the genetical variability appears as morphological variability, such as different colour forms. Where different colour forms of an animal occur in different parts of the range, the hybrid swarm is characterized by the presence of all or a wide range of these forms. |
