INTERCHROMOSOMAL EFFECTS ON SOMATIC RECOMBINATION IN DROSOPHILA MELANOGASTER

Interchromosomal Effects on Somatic Recombination in Drosophila Melanogaster.

RECOMBINATION in somatic cells of Drosophila is influenced by various genetic and environmental factors that also affect meiotic recombination. Thus, the amount of somatic crossing over in a given chromosome is controlled by the genetic contents of the chromosomal set (WEAVER 1960) and by the presence of various genes (STERN 1936; KAPLAN 1953). It may also be affected by changes in temperature ...

Interchromosomal Effects of Autosomal Translocations on Recombination in DROSOPHILA MELANOGASTER.

ETEROZYGOUS autosomal translocations have been shown to affect recomHbination in the X chromosome in various ways (HINTON 1965); translocations with long interstitial distances increased recombination in X, those with short interstitial distances decreased recombination in X, and those with intermediate interstitial distances had little or no effect. Other incidental tests of translocation hete...

The interchromosomal effect on recombination in Drosophila melanogaster

Interchromosomal Effects on Crossing over in Drosophila Melanogaster. Ii.a Reexamination of X Chromosome Inversion Effects.

NTEREST in interchromosomal effects on crossing over in Drosophila melanoIgaster has been renewed recently (COOPER, ZIMMERING and KRIVSHENKO 1955; OKSALA 1958; HART and SANDLER 1961; RAMEL 1962; SUZUKI 1962a; ROBERTS 1962). As a result of the new approaches taken in these studies, two general types of mechanisms, one physiological in nature ( STEINBERG and FRASER 1944; RAMEL 1962; ROBERTS 1962)...

Somatic Recombination within the White Locus of DROSOPHILA MELANOGASTER.

HE X-linked white locus of Drosophila melanogaster is a complex region of Tthe chromosome which has been subdivided into a number of sites (LEWIS 1952; MACKENDRICK and PONTECORVO 1952; GREEN 1959, 1964; JUDD 1959, 1964). Heterozygotes for two mutant alleles mapping at different sites in the white region (except for compounds with the right-most site, for white-spotted) do not show complementati...
