The Regulation of White Locus Expression: A Dominant Mutant Allele at the White Locus of DROSOPHILA MELANOGASTER.
A new mutant allele (w(DZL)) at the white locus of Drosophila melanogaster is dominant to the wild-type allele, but apparently only when the two alleles are synapsed. When chromosomal rearrangements prevent somatic pairing between the two white alleles, w(DZL) is rendered recessive to wild type. This observation suggests that the dominance of w(DZL) is sensitive to a synapsis (transvection) eff...
متن کاملSomatic Recombination within the White Locus of DROSOPHILA MELANOGASTER.
HE X-linked white locus of Drosophila melanogaster is a complex region of Tthe chromosome which has been subdivided into a number of sites (LEWIS 1952; MACKENDRICK and PONTECORVO 1952; GREEN 1959, 1964; JUDD 1959, 1964). Heterozygotes for two mutant alleles mapping at different sites in the white region (except for compounds with the right-most site, for white-spotted) do not show complementati...
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.
Locus of Drosophila Melanogaster
I N a previous paper (LIFSCHYTZ and FALK 1969b) we showed that by using the specific interaction pn-K-pn (prune--Killer-prune) we could construct an efficient screening system in which the products of reversions in the p n and K-pn loci were the only viable male-progeny. The few female progeny that survived served for estimating the number of tested zygotes. K p n is a dominant mutant, interact...
متن کاملMutations affecting expression of the rosy locus in Drosophila melanogaster.
The rosy locus in Drosophila melanogaster codes for the enzyme xanthine dehydrogenase (XDH). Previous studies defined a "control element" near the 5' end of the gene, where variant sites affected the amount of rosy mRNA and protein produced. We have determined the DNA sequence of this region from both genomic and cDNA clones, and from the ry+10 underproducer strain. This variant strain had many...
