“…In addition to the D. ananassae species subgroup, Franca et al (1968) reported low but significant rates of male recombination in Drosophila willistoni between two nonoverlapping paracentric inversions, so cytological evidence of male crossing over has been searched for in this species (dos Santos-Colares et al 2003. dos Santos-Colares et al (2004) stated: "In a male larva of the population G3 (from Arvoredo Island, Santa Catarina, Brazil), a heterozygote for the inversion IIL-H, involving sections 53 to 55 in the distal tip of the short arm of the second chromosome (da Cunha et al 1950), we observed in diplotene a probable consequence of chiasma in the tip of IIL chromosomal arm, suggesting the occurrence of recombination inside the inversion loop of IIL-H".…”

Spontaneous crossing over in males of Drosophila ananassae has been well demonstrated using F(1) individuals from crosses between marker stocks and wild type strains. However, the question of its occurrence in males from natural populations remained open. Here we present the cytological evidence that crossing over does occur in males of D. ananassae from two Brazilian populations, sampled nearly 21 years apart, and in two recently sampled populations, one from Indonesia and one from Okinawa, Japan. Cytological analysis of meiosis in males collected from nature and in sons of females from the same population inseminated in nature revealed the presence of chiasmata, inversion chiasmata, and isosite chromosome breakages in the diplotene cells in all sampled populations. These data demonstrate that reciprocal and nonreciprocal exchanges and chromosome breakages, previously reported as related events of male crossing over, do occur at variable frequencies among males from natural populations.

“…Low but significant rates of male recombination between two inverted segments on the second chromosome in D. willistoni had been formerly reported by FRANÇA et al (1968). A dysgenesis-like phenomenon in D. willistoni was reported by REGNER et al (1999).…”

“…Recombination between linked inversions when heterozygous has also been studied by the salivary gland smear technique in certain species of Drosophila (Carson 1953;Levitan 1958;Franca et al 1968;Singh 1973Singh , 1974. The results of these studies show that the rate of recombination varies considerably and seems to depend not only on the mechanical factor but also upon the genotype as a whole.…”

“…Their effects on crossing-over have been investigated in various species (Sturtevant 1926;Sturtevant and Beadle 1936;Glass 1933;Steinberg 1936Steinberg , 1937Steinberg and Fraser 1944;Komai andTakaku 1940, 1942;Dobzhansky and Epling 1948;Schultz and Redfield 195 1 ;Levine and Dickinson 1952;Carson 1953;Levitan 1958;Zimmering 1958;Grell 1962;Ramel 1962;Oksala 1963;Suzuki 1963;Procunier and Suzuki 1967;Franca et al 1968;Lucchesi and Suzuki 1968;Valentin 1972;Lucchesi 1976). Paracentric inversion does not include the centromere but the pericentric inversion includes the centromere within the inverted region.…”

1987. The effects of heterozygous inversions on crossing-over in Drosophila ananassae. Genome, 29: 802-805. Crossing-over was studied in females of Drosophila ananassae under different karyotypic combinations to detect the effects of heterozygous inversions by utilizing three recessive markers of the second chromosome. Because of the presence of a subterminal inversion (2L) in the heterozygous condition, crossing-over between the cu and b genes is completely eliminated. However, 2L heterozygosity enhances the level of recombination between the b and se genes. Furthermore, two third chromosome inversions when heterozygous also exert an enhancing effect on crossing-over in the second chromosome. These results provide evidence for the existence of intra-and inter-chromosomal effects of inversions on crossing-over in D.ananassae.
