Sex Chromosome Evolution, Heterochiasmy, and Physiological QTL in the Salmonid Brook Charr Salvelinus fontinalis
Whole-genome duplication (WGD) can have large impacts on genome evolution, and much remains unknown about these impacts. This includes the mechanisms of coping with a duplicated sex determination system and whether this has an impact on increasing the diversity of sex determination mechanisms. Other impacts include sexual conflict, where alleles having different optimums in each sex can result ...
متن کاملConsequences of unequal population size, asymmetric gene flow and sex-biased dispersal on population structure in brook charr (Salvelinus fontinalis).
Unravelling relationships between dispersal and population structure requires considering the impacts of assumption violations of indirect gene flow models in a given system. We combined temporal, individual and coalescent-based analyses of microsatellite DNA variation to explore the general hypothesis that unequal effective population size (Ne), asymmetric gene flow (m) and nonrandom (sex-bias...
متن کاملBehavioural Thermoregulatory Tactics in Lacustrine Brook Charr, Salvelinus fontinalis
The need to vary body temperature to optimize physiological processes can lead to thermoregulatory behaviours, particularly in ectotherms. Despite some evidence of within-population phenotypic variation in thermal behaviour, the occurrence of alternative tactics of this behaviour is rarely explicitly considered when studying natural populations. The main objective of this study was to determine...
متن کاملMajor disruption of gene expression in hybrids between young sympatric anadromous and resident populations of brook charr (Salvelinus fontinalis Mitchill).
Genome-wide analyses of the transcriptome have suggested that male-biased genes are the first targets of genomic incompatibilities (g.i.) in inter-specific hybrids. However, those studies have almost invariably focused on Drosophila species that diverged at least 0.9 Ma, and with sterile male hybrids. Here, we use microarrays to analyse patterns of gene expression in very closely related (diver...
متن کاملNeutral and selective processes shape MHC gene diversity and expression in stocked brook charr populations (Salvelinus fontinalis).
The capacity of an individual to battle infection is an important fitness determinant in wild vertebrate populations. The major histocompatibility complex (MHC) genes are crucial for a host's adaptive immune system to detect pathogens. However, anthropogenic activities may disrupt natural cycles of co-evolution between hosts and pathogens. In this study, we investigated the dynamic sequence and...
