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)...

15 صفحه اولInterchromosomal 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 کاملStudies on the Mechanism of Crossing over.
N E of the major objections to the torsion theory of crossing over as pro-0 posed by DARLINGTON (1935) is that it is difficult to comprehend why a break in one chromatid should cause a break to occur in exactly the same position in a chromatid from the homologous chromosome. This objection holds for any mechanism which postulates that crossing over occurs after the duplication of the chromosome...
