Selfing is the safest sex for Caenorhabditis tropicalis

L. M. Noble, J. Yuen, L. Stevens, N. Moya, R. Persaud, M. Moscatelli, J. Jackson, C. Braendle, E. C. Andersen, H. S. Seidel and M. V. Rockman,  bioRxiv,  2020.08.07.242032. 2020.
Frequent selfing in Caenorhabditis. tropicalis may be a strategy to avoid gene drive-mediated outbreeding depression. Mating systems have profound effects on genetic diversity and compatibility. Caenorhabditis tropicalis is the least genetically diverse among 3 species of ...

The impact of local population genetic background on the spread of the selfish element Medea-1 in red flour beetles

S. A. Cash, M. A. Robert, M. D. Lorenzen and F. Gould,  Ecology and Evolution,  12:1-12. 2019.
Selfish genetic elements have been found in the genomes of many species, yet our understanding of their evolutionary dynamics is only partially understood. A number of distinct selfish Medea elements are naturally present in many populations of the red flour beetle (Tribolium ...

The distribution and spread of naturally occurring Medea selfish genetic elements in the United States

S. A. Cash, M. D. Lorenzen and F. Gould,  Ecology and Evolution,  9:14407–14416.. 2019.
Selfish genetic elements (SGEs) are DNA sequences that are transmitted to viable offspring in greater than Mendelian frequencies. Medea SGEs occur naturally in some populations of red flour beetle (Tribolium castaneum) and are expected to increase in frequency within populations ...
