Simchuk A. P.
Frequency-Dependent Sexual Selection in a Natural Population of Oak Leafroller Moth (Tortrix viridana L.)
Cytology and Genetics 2001, v 35, number 5, 25-29
A mating system on the esterase locus Est-4 was studied in a natural population of oak leafroller moth Tortrix viridana L. Frequency-dependent sexual selection was revealed, which manifested itself in a “rare-type advantage.” On the basis of obtained data, a new hypothesis for explanation of the “rare-type advantage” phenomenon is proposed. The hypothesis proceeds from the genetically determined choice of sexual partner, depending on the degree of phenotypic likeness.
