| Summary: | The offspring of most highly fecund marine fish and shellfish suffer substantial mortality early in the life cycle, complicating prediction of recruitment and fisheries management. Early mortality has long been attributed to environmental factors and almost never to genetic sources. Previous work on a variety of marine bivalve species uncovered substantial genetic inviability among the offspring of inbred crosses, suggesting a large load of early-acting deleterious recessive mutations. However, genetic inviability of randomly bred offspring has not been addressed. Here, genome-wide surveys reveal widespread, genotype-dependent mortality in randomly bred, full-sib progenies of wild-caught Pacific oysters (Crassostrea gigas). Using gene-mapping methods, we infer that 11-19 detrimental alleles per family render 97.9-99.8% of progeny inviable. The variable genomic positions of viability loci among families imply a surprisingly large load of partially dominant or additive detrimental mutations in wild adult ... : Genotype data for four full-sib families of Pacific oyster Plough et al. 12-1-15Genotype data for parents (Sire/Dam) and offspring (Pro-1,2,3, etc), arranged by cross/family in 4 separate tabs. Data are in Join map format (CP or cross pollinator type) with the Sire and Dam highlighted in bold. Marker names run across the top in row 2 (ID). Additional information on each marker (e.g. the marker class/type and genotyping platform used) can be found in the supplementary information from Plough et al. 2016.Dryad Genotype data Plough et al 12-1-15.xlsx ... |
