Transmission of migration propensity increases genetic divergence between populations.
The advent of molecular genetics has brought invaluable information, which is now routinely used by anthropologists in their attempt to reconstruct our demographic past. Since mitochondrial DNA loci are much more similar between populations than are Y-chromosome loci, it is suggested that women had a much higher migration rate than men throughout history. Based on an examination of intergenerat...
متن کاملThe effect of Wolbachia on genetic divergence between populations: models with two-way migration.
Wolbachia are intracellular bacteria that cause various reproduction alterations in their hosts, including cytoplasmic incompatibility (CI), an incompatibility between sperm and egg that typically results in embryonic death. We investigate theoretically the effects of Wolbachia-induced bidirectional CI on levels of divergence between two populations, where there is migration in both directions ...
متن کاملGenetic divergence between Melipona quadrifasciata Lepeletier (Hymenoptera, Apidae) populations
Melipona quadrifasciata is a stingless bee widely found throughout the Brazilian territory, with two recognized subspecies, M. quadrifasciata anthidioides, that exhibits interrupted metasomal stripes, and M. quadrifasciata quadrifasciata, with continuous metasomal stripes. This study aimed to estimate the genetic variability of these subspecies. For this purpose, 127 colonies from 15 Brazilian ...
متن کاملEpistasis and the genetic divergence of photoperiodism between populations of the pitcher-plant mosquito, Wyeomyia smithii.
Parallel crosses between each of two southern (ancestral) and one northern (derived) population of the pitcher-plant mosquito, Wyeomyia smithii, were made to determine the genetic components of population divergence in critical photoperiod, a phenological trait that measures adaptation to seasonality along a climatic gradient. Joint scaling tests were used to analyze means and variances of firs...
متن کاملGenetic divergence between cave and surface populations of Astyanax in Mexico (Characidae, Teleostei).
A study of genetic diversity at microsatellite loci and the mitochondrial DNA (mtDNA) cytochrome b gene was carried out to assess genetic relationships among four Mexican cave (Pachon, Sabinos, Tinaja, Chica) and four surface populations of Astyanax fasciatus (Characidae) from northeast Mexico and the Yucatan. With the exception of Chica, the cave populations were all characterized by extremely...
