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)...
متن کاملInterchromosomal effects on crossing-over in Drosophila melanogaster. I. Effects of compound and ring X chromosomes on the third chromosome.
LTHOUGH the properties of crossing-over have been investigated extenA sively in Drosophila melanogaster, the influence of nonhomologous chromosomes on crossing-over is a problem that warrants further exploration. Since STURTEVANT’S (1919) observation that a heterozygous inversion in the third chromosome increased crossing-over in chromosome 2, many investigators such as SCHULTZ and REDFIELD in ...
متن کاملEffects of Mitomycin C on Crossing over in Drosophila Melanogaster.
RECENT evidence indicates that a large proportion of increases in crossing over induced in Drosophila melanogmter females is of gonia1 ongin (WHITTINGHILL 1955; THOMPSON 1964; SUZUKI 1965). HOLLIDAY (1964) and ESPOSITO and HOLLIDAY (1964) find that treatment of Ustilago and Saccharomyces with agents that inhibit DNA replication (mitomycin C, 5-fluorodeoxyuridine) results in increased somatic re...
متن کاملEffects of Actinomycin D on Crossing over in Drosophila Melanogaster.
STUDIES on crossing over are usually designed to correlate changes in crossover values with a specific genetic or environmental condition. The lack of understanding of the primary genetic effects of chromosome rearrangements makes inferences based on the effects of these aberrations on crossing over difficult ( SUZUKI 1963b). On the other hand, extrinsic factors (temperature, radiation, chemica...
متن کاملInterchromosomal 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...
