An unusual pattern of interchromosomal effect in Drosophila melanogaster

The interchromosomal effect on recombination in Drosophila melanogaster

Lack of an Interchromosomal Effect Associated with Spontaneous Recombination in Males of Drosophila Melanogaster

It is shown that the frequency of spontaneous male recombination in two different lines of Drosophila melanogaster (OKI and T-007) are not subject to an interchromosomal effect. Second-chromosome male recombination in these lines was not affected by heterozygosity for the multiple third-chromosome inversions In(3LR)TM3 or In(3LR)Ubx, which do affect recombination in females. It seems, therefore...

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 ...

An F1 genetic screen for maternal-effect mutations affecting embryonic pattern formation in Drosophila melanogaster.

Large-scale screens for female-sterile mutations have revealed genes required maternally for establishment of the body axes in the Drosophila embryo. Although it is likely that the majority of components involved in axis formation have been identified by this approach, certain genes have escaped detection. This may be due to (1) incomplete saturation of the screens for female-sterile mutations ...
