Inversion polymorphisms often have been associated with fitness variation. Cactophilic Drosophila buzzatii has been used widely for the study of the maintenance of chromosomal variation. The purpose ...

Substantial allele-frequency changes were observed at the Adh and αGpdh loci in a seminatural population of Drosophila melanogaster kept in a tropical greenhouse during 1972-1985. Further analysis of ...

Researchers have been tracking the evolution of Drosophila subobscura, a small fly that is very common all over Europe, since 1976. They are focusing on a specific type of genomic variability known as ...

Researchers at deCODE Genetics in Reykjavik, Iceland, have discovered a large chromosomal rearrangement in the human genome that appears to have been selected for in some European populations. 1 The ...
