DeBry* and William F. Manlufft *Department of Biological Science, Florida State University, Tallahassee, Florida 32306-2043, and tProgram an Molecular Biology ~~~
- Correlation between pairing initiation sites, recombination nodules and meiotic recombination in Sordaria macrospora....Copyright Q 1992 by the Genetics Society of America Correlation Between Pairing Initiation Sites, Recombination Nodules and Meiotic Recombination in Sordaria macrospora Denise Zickler, Patrick J. F. Moreau, Anh Dao Huynh and Anne-Marie Slezec Znstitut de Cinitique et Microbiologie, Uniuersiti Paris ~~~
- Identification of target genes regulated by homeotic proteins in Drosophila melanogaster through genetic selection of Ultrabithorax protein-binding sites in yeast....Copyright 0 1995 by the Genetics Society of America Identification of Target Genes Regulated by Homeotic Proteins in Drosophila melanogaster Through Genetic Selection of Ultrabithorax Protein-Binding Sites in Yeast Grant S. Mastick, '** Renee McKay, Thomas Oligino, Katya Donovan and A. Javier Lopez ~~~
- Estimates of linkage disequilibrium and the recombination parameter determined from segregating nucleotide sites in the alcohol dehydrogenase region of Drosophila pseudoobscura....Copyright 0 1993 by the Genetics Society of America Estimates of Linkage Disequilibrium and the Recombination Parameter Determined From Segregating Nucleotide Sites in the Alcohol Dehydrogenase Reson of Drosophila pseudoobscura Stephen W. Schaeffer and Ellen L. Miller Department of Biology ~~~
- The detection of linkage disequilibrium in molecular sequence data....ABSTRACT Studies of genetic variation in natural populations at the sequence level usually show that most polymorphic sites are very asymmetrical in allele frequencies, with the rarer allele at a site near fixation. When the rarer allele at a site is present only a few times in the sample, say below five ~~~
- In situ hybridization analysis of chromosomal homologies in Drosophila melanogaster and Drosophila virilis....virilis. All probes hybridized to D. melanogaster chromosomes at the expected sites. However, one probe hybridized to at least 16 additional sites, and one hybridized to one additional site. Thirteen probes hybridized strongly to D. virilis chromosomes, four hybridized weakly and infrequently, and seven ~~~
- Population genetics of polymorphism and divergence..... Louis, Missouri 631 10 Manuscript received March 7 , 1992 Accepted for publication August 12, 1992 ABSTRACT Frequencies of mutant sites are modeled as a Poisson random field in two species that share a sufficiently recent common ancestor. The selective effect of the new alleles can be favorable, neutral ~~~
- The Tn3 beta-lactamase gene acts as a hotspot for meiotic recombination in yeast....-PYKZ interval of chromosome Z has about 5-fold more crossovers than an average interval (COLEMAN et al. 1986) and the LEU2-HIS4 interval of chromosome ZZZ is about %fold hotter than the average (NEWLON et al. 1986). A 2.9-kb region of chromosome ZZZ (between the G3 and B sites in Figure 1 ~~~
- Estimating substitution rates in ribosomal RNA genes....at nucleotide sites are assumed to follow gamma distributions that are different for the two types of regions. The simplest formulation of the model allows for explicit expressions for transition probabilities of the Markov processes to be found. These expressions were used to analyze several 16Slike rRNA genes ~~~
- A ubiquitin-conjugating enzyme, RAD6, affects the distribution of Ty1 retrotransposon integration positions..... These results show that the ubiquitin-conjugating enzyme, RADG, alters the integration site preferences of T y l retrotransposons. T HE insertion of retroviruses and retrotranspos- ons into the host genome is independent of homology between the ends of the elements and the sites of the insertion ~~~
