comparative assessment of genetic diversity of 122 durum wheat genotypes (triticum turgidum l. var. durum) was performed using 73 ssap polymorphic fragments, 123 aflp polymorphic loci and 104 ssr alleles. ssap and aflp data showed a clear demarcation between the cultivars and landraces and ssr data classified cultivars and landraces according to their origin. furthermore, the estimated genetic ...

Based on a wide range of direct and indirect evidence, particularly work by Klaus Eyferth and James Flynn, the author concludes that the black-white gap is not substantially genetic in orgin. In studies in 1959 and 1961, Eyferth first pointed to the near-disappearance of the black-white gap among children of black and white servicemen raised by German mothers after World War II. In the author’s...

T his report is one product of a large project un-dertaken by The Hastings Center and the Amer-ican Association for the Advancement of Science and funded by the Ethical, Legal, and Social Implications division of the National Human Genome Research Institute. Mark Frankel and Audrey Chap-man (from AAAS) and I worked from the very beginning to develop the project and submit the grant application ...

Genetic polymorphisms of drug metabolizing enzymes are well recognized. This review presents molecular mechanisms, ontogeny and clinical implications of genetically determined intersubject variation in some of these enzymes. Included are the polymorphic enzymes N-acetyl transferase, cytochromes P4502D6 and 2C, which have been well described in humans. Information regarding other Phase I and Pha...
