Metaphase Configurations In Drosophila: A Comparison Of Endemic Hawaiian Species And Non-Endemic Species, Frances E. Clayton
Metaphase Configurations In Drosophila: A Comparison Of Endemic Hawaiian Species And Non-Endemic Species, Frances E. Clayton
Journal of the Arkansas Academy of Science
The metaphase configurations of 400 strains from 63 species of Hawaiian Drosophila were determined from squash preparations of larval brain tissue or spermatogenic cells from adult testes. These karyotypes include configurations from seven species not previously described. Metaphases of 148 Hawaiian species have been recorded, including species of the "picture-wing" group, the "modified mouthpart" group, and the "bristle-foot" group. A comparison between Hawaiian species and non-endemic species was made on the basis of chromosome numbers and configurations. Among the Hawaiian species, 85.8% have retained the primitive haploid configuration of five rods and one dot compared with only 34.8% of species …
Electrophoretic Patterns Of Serum Proteins In Two Subspecies Of Odocoileus Virginianus, Greg S. Jackman, Phyllis J. Garnett
Electrophoretic Patterns Of Serum Proteins In Two Subspecies Of Odocoileus Virginianus, Greg S. Jackman, Phyllis J. Garnett
Journal of the Arkansas Academy of Science
Cellulose acetate electrophoresis revealed six monomorphic forms of serum protein in natural populations of two subspecies of white-tailed deer, Odocoileus virginianus virginianus from Tennessee and Odocoileus virginianus macroura from Arkansas. The fixed pattern of serum proteins in the two populations indicates a lack of genetic variation in the loci controlling these proteins. However, electrophoresis revealed different hemoglobin phenotypes in the two subspecies. This finding indicates that further study is needed to determine whether or not there are genetic differences in the hemoglobin forms
Study Of Ultraviolet-Induces Chromatid And Chromosome Aberrations As A Function Of Dose In G1 Phase Vertebrate Tissue Cultures, Troy V. Orr, H. Gaston Griggs
Study Of Ultraviolet-Induces Chromatid And Chromosome Aberrations As A Function Of Dose In G1 Phase Vertebrate Tissue Cultures, Troy V. Orr, H. Gaston Griggs
Journal of the Arkansas Academy of Science
G1 phase A8 Xenopus laevis (toad) and V79B Cricetulus griseus (hamster) tissue cultures were used to observe the frequency of ultraviolet-induced chromosomal aberrations as a function of dose. When cultures are irradiated with ultraviolet light, visible aberrations are virtually absent until a threshold of approximately 80 ergs mm⁻¹ is reached. Aberrations then occur as a nonlinear function of dose. Chromatid aberrations are by far the most prevalent until doses in excess of 200 ergs mm⁻¹ are administered, at which point chromosome aberrations become common.
The Feral Goat Herd Of Faure Island, W H J Clarke
The Feral Goat Herd Of Faure Island, W H J Clarke
Journal of the Department of Agriculture, Western Australia, Series 4
For just on a century there has existed on Faure Island, off the mid Western Australian coast, a herd of white feral goats.
The fleece of these animals, while similar in appearance to Angora mohair, has characteristics which somewhat resemble the luxury fibre cashmere, in that it comprises a fine dense undercoat, which sheds in early spring, as well as the hairy outcoat typical of all goat breeds except the Angora.
As there is little, if any, shedding in second or subsequent crosses, it would appear that the mating of Faure Island feral goats with traditional Angoras (or off-spring of …
