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 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...

B ECAUSE triploid females form large numbers of chromosomally unbalanced eggs it is possible to recover complementary types of unbalanced sperm. This technique revealed the occurrence of autosomal nondisjunction in males (STERN 1934; PONTECORVO 1940) and was also used by MULLER and PONTECORVO ( 1940) and PONTECORVO (1943) to recover sperm where radiation induced chromosome breaks caused one or ...
متن کاملThe Effect of Autosomal Inversions on Crossing over in the X-Chromosome of Drosophila Melanogaster.
HE first evidence of a crossover suppressor was found in 1913 by T STURTEVANT. In 1921 STURTEVANT found the first definite evidence of an inversion when he showed that several third chromosome genes in Drosophila melanogaster were arranged in an inverted order with respect to similar genes in the third chromosome of D. simulans. At this time STURTEVANT predicted that a heterozygous inversion wo...
