The article is devoted to quantitative characteristics of assortative mating (R) as indicator of "reinforcement" in 12 hybrid zones between chromosomal races of the common shrew, Sorexaraneus L. The Wahlund effect in hybrid population and its potential reduction are examined. In hybrid zones with heterozygotes CIV, CV, and RIV, the R index varies within 0.23–0.59. In hybrid zones with more complex heterozygotes (RVI, CIX–CXI), it exceeds 0.82. Gene flow in the hybrid zone is interrupted at R > 0.99. Assortative mating reduces gene flow and also maintains genotype stability in hybrid populations. [ABSTRACT FROM AUTHOR] |
