Impact of Intraspecific Polyploidy in Andropogon gerardii(Poaceae) Populations

—Andropogon gerardii populations are comprised of two (or more) polyploid forms over much of the range of the species. To understand the impact of intraspecific polyploidy, polyploid cytotypes were compared over 4 y in native grasslands in Boulder, Colorado. Boulder A. gerardii populations averaged 59.6% hexaploids (60 chromosomes), 35.3% enneaploids (90 chromosomes) and 5.1% intermediate (aneu...

Diverse forms of selection in evolution and computer science.

The astonishing diversity of complex adaptations that we see in the living world has been produced by natural selection, over ∼3.5 billion years of evolution. Information from the largely random survival and reproduction of past organisms has accumulated to produce genomes that are precisely fitted to diverse environments. In PNAS, Chastain et al. (1) show that natural selection on freely recom...
