Sex-specific effects of inbreeding in juvenile brown trout

Inbreeding depression, i.e., the reduction of health and vigour in individuals with high inbreeding coefficients, is expected to increase with environmental, social, or physiological stress. It has therefore been predicted that sexual selection and the associated stress usually lead to higher inbreeding depression in males than in females. However, sex-specific differences in life history may reverse that pattern during certain developmental stages. In some salmonids, for example, female juveniles start developing their gonads earlier than males who instead grow faster. We tested whether the sexes are differently affected by inbreeding during that time. To study the effects of inbreeding coefficients that may be typical for natural populations of brown trout (Salmo trutta), and also to control for potentially confounding maternal or paternal effects, we sampled males and females from the wild, used their gametes in a block-wise full-factorial breeding design to produce 60 full-sib famil..., See methods in: Bylemans, J., Marques da Cunha, L., Sarmiento Cabello, S., Nusbaumer, D., Uppal, A. and Wedekind, C.

For all but two breeders (one dam and one sire) high quality DNA extracts or tissue samples could be used for whole genome resequencing to calculate the kinship coefficients for each breeding pair; the corresponding VCF file contains the relevant data.
