Coming To Terms With Heritability, Scott F. Stoltenberg
Coming To Terms With Heritability, Scott F. Stoltenberg
Department of Psychology: Faculty Publications
The complex mechanisms of heredity are little appreciated by nonspecialists, in some measure, because of misunderstandings that are perpetuated when words used for technical terms have other, more widely understood, folk meanings. When a word has both technical and folk meanings, it is the responsibility of the specialist to avoid promoting confusion by either using extremely cautious and precise language when using the term or, in cases when confusion is inevitable, abandoning the term in favor of one without a widely understood folk meaning. The study of heredity is beset by such confusion, and the term heritability appears to be …

Review Of Retracing Major Stephen H. Long's Expedition: The Itinerary And Botany By George J. Goodman And Cheryl A. Lawson, Robert B. Kaul
Great Plains Research: A Journal of Natural and Social Sciences
Earlier expeditions made incidental collections of plants and animals in Louisiana Territory, but the Long Expedition of 1820 was the first deliberately staffed with scientists assigned to that task. Authorized by President Monroe and Secretary of War Calhoun, the Expedition was directed to document plant and animal life and geology in the intimidating country between the Missouri River and the Rocky Mountains and to find the source of the Platte and Red Rivers in the mountains. All this was to be done quickly and, in fact, took only 100 days, June 6-September 13, 1820. Starting near present-day Omaha, the Expedition …
Y-Chromosome Effects On Drosophila Geotaxis Interact With Genetic Or Cytoplasmic Background, Scott F. Stoltenberg, Jerry Hirsch
Y-Chromosome Effects On Drosophila Geotaxis Interact With Genetic Or Cytoplasmic Background, Scott F. Stoltenberg, Jerry Hirsch
Department of Psychology: Faculty Publications
Previously, all of the major fruit fly, Drosophila melanogaster, chromosomes (I, II, and III) have been shown to be associated with geotaxis, but the Y chromosome has not. Using two methods (back-crossing and chromosome substitution), Y chromosomes from lines that have evolved stable, extreme expressions of geotaxis were placed into different genetic and cytoplasmic backgrounds to test the resulting males for geotaxis. The results of the back-crossing do not support the interpretation of Y-chromosome effects on geotaxis. These tests do not have sufficient statistical power, however, to detect small genetic effects. In the chromosome substitution experiment, the geotaxis-line Y …
