Web摘要： Population genetics allow to address fundamental questions about the biology of plant pathogens. By testing specific hypotheses, population genetics provide insights into the population genetic variability of pathogens across different geographical areas, time, and associated plant hosts, as well as on the structure and differentiation of populations, … WebTwo populations of flowering plants live in neighboring areas and can experience pollination across the populations. In one population, individuals with phenotype P are most common (PP=2000, Pp=200, pp=20). In the other population, the other phenotype (p) is more common (PP=20, Pp=200, pp=2000).
