| detection of stabilizing selection in favor of the santa cruz homokaryotype in drosophila pseudoobscura populations from the high plateau of the colombian andes. | chromosome 3 rearrangements were studied in five drosophila pseudoobscura populations from the high plateau of the colombian andes. as in previous studies, the santa cruz and tree line rearrangements were predominant in these populations, but for the first time other rearrangements such as the olympic, cuernavaca and a rearrangement similar to the endemic mexican amecameca rearrangement were also discovered. researchers in the early 1960's showed that colombian d. pseudoobscura populations were ... | 2002 | 14963809 |
