joint effects of natural selection and recombination on gene flow between drosophila ananassae populations. | we estimated dna sequence variation in a 5.7-kb fragment of the furrowed (fw) gene region within and between four populations of drosophila ananassae; fw is located in a chromosomal region of very low recombination. we analyzed gene flow between these four populations along a latitudinal transect on the indian subcontinent: two populations from southern, subtropical areas (hyderabad, india, and sri lanka) and two from more temperate zones in the north (nepal and burma). furthermore, we compared ... | 2000 | 10880480 |
