INTERCHROMOSOMAL EFFECTS OF INVERSIONS IN DROSOPHILA MELANOGASTER

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...

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 ...

Exchange within heterozygous inversions in Drosophila melanogaster.

The exchange behavior of non-attached, whole arm, X chromosome inversions was reexamined using nondisjunction in XXY females as an indirect measure of the frequency of nonexchange tetrads. Crossing over is quite normal in these inversion heterozygotes and is independent of the arrangement of the basal heterochromatin.

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)...
