Linking transcriptomic and genomic variation to growth in brook charr hybrids (Salvelinus fontinalis, Mitchill).

ABSTRACT: Hybridization can lead to phenotypic differences arising from changes in gene expression patterns or new allele combinations. Variation in gene expression is thought to be controlled by differences in transcription regulation of parental alleles, either through cis- or trans-regulatory elements. A previous study among brook charr hybrids from different populations (Rupert, Laval, and domestic) showing distinct length at age during early life stages also revealed different patterns in transcription regulation inheritance of transcript abundance. In the present study, transcript abundance using RNA-sequencing and quantitative real-time PCR, single-nucleotide polymorphism (SNP) genotypes and allelic imbalance were assessed in order to understand the molecular mechanisms underlying the observe
