The Pennsylvania grotto sculpin: population genetics

نویسندگان

چکیده

The Pennsylvania grotto sculpin is known from just two caves of the Nippenose Valley in central Pennsylvania, USA. They exhibit emergent troglobitic morphological traits and are second northern-most cave adapted fish world. Two mitochondrial ( 16S rRNA D-loop gene) one nuclear S7 ribosomal protein gene intron) both epigean populations were sequenced. For three markers, a large proportion specimens possess unique haplotypes not found their local surface counterparts, suggesting vicariance evolutionary history. population also has separate lineages sculpins Cottus cognatus / bairdii species complex. Since morphology, nuclear, markers correlated among individuals, hybridization with introgression suggested.

Evolutionary Genetics Theoretical Population Genetics

Evolutionary genetics studies the patterns and mechanisms of genetic changes underlying evolutionary change. Because biological diversity at all levels (including population, species, and ecosystem diversity) has a genetic basis and is a result of evolution, evolutionary genetics provides insight into the ultimate mechanisms creating biodiversity. Evolutionary genetics utilizes empirical tools ...

Population genetics

Population genetics is the study of genetic variability within a population and of the forces that act upon it. As well as being of central importance to our understanding of evolution from prehistoric to modern times, it now also affects our everyday lives — whether considering human genetic disease, how to avoid the extinction of rare species or the merits of ‘DNA fingerprinting’ in forensic ...
