摘要：

Strong gametic disequilibrium between allozyme loci and sex chromosomes exists in natural populations of four Rhagoletis species, and weak disequilibrium exists in two other species. The disequilibrium is possible because of (1) extensive homology of X and Y chromosomes and (2) restricted crossing over in male Rhagoletis. One of the species displaying strong disequilibria, R. suavis, must be female heterogametic, although direct cytogenetic evidence is not yet available. Forces responsible for the evolution of the disequilibrium are discussed.
