Mapping vertebrate incompatibility alleles Deleterious gene interactions may underlie the observed hybrid incompatibilities. However, few genes underlying incompatibilities have been identified, and most of these involve species that do not hybridize in natural conditions. Powell et al. used genome sequencing to map likely responsible for reduce fitness naturally occurring swordtail fish. These combinations result malignant melanoma, which is found hybridizing populations but present...
Abstract Social rank in a hierarchy determines which individuals have access to important resources such as food, shelter, and mates. In the African cichlid fish Astatotilapia burtoni , is under social control, that larger males are more likely than smaller be dominant rank. Although it well known relative size of A . critical controlling rank, specific behaviors underlying responses different sizes not understood. many other species, when asymmetries between competing small, physical...
ABSTRACT Natural selection shapes traits during evolution including animal coloration known to be important for concealment and communication color has been particularly salient in the explosive radiation of cichlid fish species rift valley lakes East Africa. Though can produce variation via genetic substrates early development, plasticity occur through endocrine, neural transcriptional cues response various environmental stimuli. It is well that some animals often change match their visual...
Abstract The establishment of reproductive barriers between populations is the key process that fuels evolution new species. A genetic framework for this was proposed over 80 years ago, which posits “incompatible” interactions genes result in reduced survival or reproduction hybrids. Despite foundational work, progress has been slow identifying individual underlie hybrid incompatibilities, with only a handful known to date. Here, we use combination approaches precisely map drive development...
