Polyploidy (the multiplication of chromosome sets within a nucleus) and apomixis (the production of embryos without fertilization) are encountered in many living organisms. Their roles in the propagation of hybrids (in wheat, cotton, citrus, etc.) are well documented, but their effects on genetic diversity and geographic distribution are largely unexplored. Polyploidy and apomixis are especially prevalent in cheilanthoid ferns, a group of 500+ species adapted to seasonally dry habitats avoided by most other ferns, and they clearly have contributed to the ability of these species to prosper in these climatically-challenged environments. Using a combination of genetic (DNA, protein, and chromosome) and morphological analyses, this project will explore this apparent connection between polyploidy and apomixis, genetic diversity, and the ability to colonize marginal habitats.
