The 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...
متن کاملInterchromosomal 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 کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
