Genomic evidence that a sexually selected trait captures genome-wide variation and facilitates the purging of genetic load - Nature.com

Populations of a bulb mite that were experimentally selected for a male weapon showed reduced diversity across the genome, indicating that strong sexual selection increases the strength of purifying selection.

For a schematic overview of the experimental design, see Fig. 2. Experimental evolution Protocol The stock population (Stock population below) was allowed to expand for one generation and from thi… [+43029 chars]
