Abstract
Genetic recombination between ap and dc autosomal loci is 18.8 and 21.6% in heterozygous Mediterranean fruit fly, Ceratitis capitata (Wiedemann), females (in coupling and repulsion, respectively), and rare or nonexistent in heterozygous males. The introduction of a Y-autosome translocation in the Mediterranean fruit fly males triggered the occurrence of 0.15 and 1.98% recombination between the two loci in heterozygous males carrying the translocation. The effect of genetic recombination in males on automated sexing methods is discussed.
