Conservation genomics of Atlantic salmon: variation in gene expression between and within regions of the Bay of Fundy.

abstract：:We investigated whether birth weight and neonatal survival, a period within which 24% of all mortalities occur, were correlated with levels of inbreeding in St Kilda Soay sheep, using pedigree inbreeding coefficients and four marker-based estimators of inbreeding. None of the inbreeding estimators, either of the offsp...
