Genetic Markers as Coordinates of Population Motion

Genetic markers such as the Rh (Rhesus) blood group are often discussed or received as indicators of ancestral purity or fixed biological identity. This paper advances a complementary framing: low-dimensional genetic markers function as coordinates of population motion, reflecting differential rates of admixture, isolation, and continuity over time. Rather than encoding static ancestral states, these markers preserve signals of relative persistence under constrained gene flow. This framing aligns population genetics with the inherently non-stationary nature of living systems and clarifies how biology, culture, geography, and time jointly shape human genetic landscapes. population genetics, genetic markers, Rh factor, blood group genetics, founder effects, isolation by distance, genetic drift, admixture dynamics, human migration, population continuity, gene flow, ancestry interpretation, dynamic systems, non-stationary biology, fractal population structure, allele frequency attenuation, population structure, demographic history, ancient DNA, modern genomics, evolutionary neutrality, low-dimensional markers, haplogroups, Y-chromosome variation, mitochondrial DNA, cultural barriers to gene flow, geographic constraints, mating networks, demographic bottlenecks, population expansion, signal preservation, genetic continuity models, dilution models, isolation-by-distance models, systems biology, statistical genetics, population kinematics, historical demography, regional endogamy, admixture rates, genetic clustering, principal component analysis, ancestry modeling, reference populations, theoretical purity, evolutionary timescales, human population history, genomic variation, neutral variation, interpretive frameworks
