Weddell seal genomes, Erebus Bay Antarctica
Within any population, some individuals perform better than others. These individuals may survive longer or produce more offspring. Weddell seals in Erebus Bay, Antarctica, provide an unparalleled opportunity to investigate how an animal's physiology, behavior, and genetic make-up contribute to lifetime reproductive success because they have been the subject of a long-term population monitoring study and are easily accessible during their reproductive season. This study examined whole genome sequences of 46 adult female Weddell seals with the goal of linking genomic data with physiology and reproductive success.
