| 词条 | Ecotypic variation |
| 释义 |
In population genetics, ecotypic variation is the type of genetic variation found in a large continuous geographic populations. Variation of this kind is homogeneous, due to factors such as gene flow. In 1954 Ernst Mayr wrote a landmark paper attacking the idea that subspecies in ecotypic populations lead to formation of incipient species.[1] According to Mayr species formation occurred in populations which were small and isolated, that is, populations which exemplified typostrophic variation.
