The genetic diversity of a population was determined using polymorphic microsatellite markers to verify whether the species is actually producing new individuals through sexual reproduction. KEY RESULTS: Japanese knotweed produces, in Quebec, a large number of seeds with a high germination rate (up to...
Sexual reproduction likely evolved as protection from environmental stresses, specifically, to repair DNA damage, often via homologous recombination. In higher eukaryotes, meiosis and the production of gametes with allelic combinations different from parental type provides the side effect of increased genetic...
and I just want to give you one very short poemfrom eighth-century China,because it’s an almost perfect exampleof a man who is focused totally on a particular woman.It’s a little bit like when you are madly in love with somebodyand you walk into a parking lot --their car...
For example, in self-incompatible plants, mixtures of self and interspecific pollen often induce selfing. Here, we examine patterns of mating in three ... LH Rieseberg - 《Evolution》 被引量: 525发表: 0年 Pollinator-mediated assortative mating in mixed ploidy populations of Chamerion angustifolium...
