Linkage disequilibrium mapping of the bolting gene in sea beet using AFLP markersGenetical Research - Tập 77 Số 1 - Trang 61-66 - 2001
Mats Hansen, Thomas Kraft, SARA GANESTAM, Torbjörn Säll, Nils‐Otto Nilsson
The possibility of using linkage disequilibrium mapping in natural plant populations was assessed.
In studying linkage disequilibrium among 137 mapped AFLP markers in four populations of sea
beet (Beta vulgaris ssp. maritima (L.) Arcang.) it was shown that tightly linked loci could be
detected by screening for associations. It was hy...... hiện toàn bộ
A world-wide survey of genetic variation in the yellow fever mosquito,Aedes aegyptiGenetical Research - Tập 34 Số 3 - Trang 215-229 - 1979
Walter J. Tabachnick, Jeffrey R. Powell
SUMMARYThirty-four populations ofAedes aegyptirepresenting the world-wide distribution of the species, were analysed for genetic variation at 19–22 isozyme loci. The species has an average expected heterozygosity of 0·129±0·045 based on 19 loci analysed in every population. Based on this genetic information, two major groups can be define...... hiện toàn bộ
Mitotic non-conformity inAspergillus: successive and transposable genetic changesGenetical Research - Tập 16 Số 1 - Trang 79-93 - 1970
João Lúcio de Azevedo, J. A. Roper
SUMMARYStrains ofAspergillus nidulanswith, a duplicate chromosome segment are mitotically unstable; in addition to phenotypically improved variants, arising following deletions in either duplicate segment, they give morphologically deteriorated types, some with, enhanced stability. In one isolate, deterioration and increased instability w...... hiện toàn bộ
The genetics of tasting in mice: V. Glycine and cycloheximideGenetical Research - Tập 52 Số 3 - Trang 207-212 - 1988
Ian E. Lush, Gail Holland
SummaryGlycine tastes both bitter and sweet to mice but there are differences between strains in their ability to detect each taste. With respect to the bitter taste, fifteen strains were classified as tasters and twelve strains as non-tasters. The difference is due to a single gene, Glb (glycine bitterness). Cycloheximide tastes bitter t...... hiện toàn bộ
Non-stringent tissue-source requirements for BMP ligand expression in regulation of body size inCaenorhabditis elegansGenetical Research - Tập 93 Số 6 - Trang 427-432 - 2011
Cathy Savage‐Dunn, Ling Yu, KWESI GILL, Muhammad Uzair Awan, Thilini R. Fernando
SummaryInCaenorhabditis elegans, the Bone Morphogenetic Protein (BMP)-related ligand Dpp- and BMP-like-1 (DBL-1) regulates body size by promoting the larval and adult growth of the large epidermal syncytium hyp7 without affecting cell division. This system provides an excellent model for dissecting the growth-promoting activities of BMP l...... hiện toàn bộ
Polymorphism in a varied environment: how robust are the models?Genetical Research - Tập 35 Số 1 - Trang 45-57 - 1980
J. Maynard Smith, R. Hoekstra
SUMMARYThis paper shows that a number of models of the maintenance of polymorphism in a heterogeneous environment, including those of Levene and Dempster, can be derived from a simple assumption about the way in which the numbers and kinds of individuals emerging from a niche depend on the number of eggs laid in it. It is shown that for such models, unless selectiv...... hiện toàn bộ
