the process in nature by which forms of life having traits that better enable them to adapt to specific environmental pressures, as changes in climate or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind, thus perpetuating those traits...

Population differences exist in the presence of molar crenulations, which were likely shaped by evolution. Based on these results molar crenulations can be added to the suite of traits currently used to study population differences.doi:10.1016/j.jchb.2018.06.001M.A. Pilloud...

The sibling distribution of (additive) polygenic scores (PGS) for such traits is centered at the parental midpoint 2. The sibling genetic variance is roughly half that found in the general population (i.e., of individuals who are not closely related to each other). The probability distributi...
Building an understanding of the genetic and epigenetic architecture that underlies the variation of gene expression traits addresses a core problem in genetics. It also impacts many applications in plant breeding, including the mechanism of hybrid vigor (heterosis) and the performance and stability of...
Variation in Population and Life History Traits of the American Eel, Anguilla rostrata, in Four Rivers in Maine We examined population traits of yellow American eels from nine sites with similar habitat characteristics in each of four rivers in Maine, U.S.A. Migratin... K Oliveira,JD Mccleav...
Genetic variation can be defined as the genetic makeup of organisms within a population change. Genes are inherited segments of DNA that contain codes for the production of proteins. Genes exist in alternate versions, or alleles, that determine distinct traits that can be passed on from parents ...
