Two esterase loci, Est-4 and Est-5, in Aedes albopictus encode carboxylesterases in 4th-instar larvae, pupae and adults. The electrophoretic bands migrate on agar gels toward the most anodal side, those of Est-5 followed by those of Est-4. Linkage studies on the two loci revealed that they were arranged on linkage group 2 in the following order: Est-4-(0.9 +/- 0.7 to 4.3 +/- 1.4 map units)-p(pi...
A 356-marker linkage map of Glycine max (L.) Merr. (2n = 20) was established by anchoring 106 RAPD markers to an existing RFLP map built with a large recombinant inbred line population (330 RILs). This map comprises 24 major and 11 minor linkage groups for this genome which is estimated to be approximately 3,275 cM. The RAPD markers show similar distribution throughout the genome and identified...
Interspecies hybrids between distinct species of the genus Xiphophorus are often used in varied research investigations to identify genomic regions associated with the inheritance of complex traits. There are 24 described Xiphophorus species and a greater number of pedigreed strains; thus, the number of potential interspecies hybrid cross combinations is quite large. Previously, select Xiphopho...
The results of genotypic data contributed to the International Society for Animal Genetics (ISAG) Bovine Chromosome 27 Workshop are presented. Eight laboratories contributed 23 261 informative meioses from 44 loci. Eighteen loci were typed by at least two laboratories and were used to construct a consensus linkage map. Twenty-one loci were subsequently incorporated into a comprehensive map. The...
The silkworm (Bombyx mori L.) is a lepidopteran insect with a long history of significant agricultural value. We have constructed the first amplified fragment length polymorphism (AFLP) genetic linkage map of the silkworm B. mori at a LOD score of 2.5. The mapping AFLP markers were genotyped in 47 progeny from a backcross population of the cross no. 782 x od100. A total of 1248 (60.7%) polymorp...
A unidimensional nonnegative scaling model is used to construct linkage disequilibrium (LD) maps for human genome. The proposed constrained scaling model can be solved efficiently by transforming it to an unconstrained model. A LD map based on Hapmap data of 50000 SNPs is constructed by the proposed method using PC Clusters.
To facilitate molecular genetic analysis of vertebrate development, haploid genetics was used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map consists of 401 random amplified polymorphic DNAs (RAPDs) and 13 simple sequence repeats spaced at an average interval of 5.8 centimorgans. Strategies that exploit the advantages of haploid genetics and RAPD markers w...
We report the most extensive genetic linkage map for a livestock species produced to date. We have linked 376 microsatellite (MS) loci with seven restriction fragment length polymorphic loci in a backcross reference population. The 383 markers were placed into 24 linkage groups which span 1997 cM. Seven additional MS did not fall into a linkage group. Linkage groups are assigned to 13 autosomes...
