Weak genetic divergence and signals of adaptation obscured by high gene flow in an economically important aquaculture species.

ABSTRACT:

Background

The genetic diversity of a population defines its ability to adapt to episodic and fluctuating environmental changes. For species of agricultural value, available genetic diversity also determines their breeding potential and remains fundamental to the development of practices that maintain health and productivity. In this study, we used whole-genome resequencing to investigate genetic diversity within and between naturalized and captively reared populations of Pacific oysters from the US Pacific coast. The analyses included individuals from preserved samples dating to 1998 and 2004, two contemporary naturalized populations, and one domesticated population.

Results

Despite high overall heterozygosity, there was extremely low but significant genetic divergence betw
