Outcrossing Guppies: The Rare Male Advantage

My new article ‘Outcrossing: The Rare Male Advantage’ discusses how the female guppy’s decided preference for novel males can help in outcrossing. Females quickly turn over paternity to new males rather than stored sperm from familiar males. Article discusses my successful outcrosses and the impressive scientific and experimental basis for the ‘The Rare Male Advantage’ in guppies. This subject has widespread implications for evolution, speciation, and maintaining genetic heterozygosity in natural populations.
