"Advances in Genetics Research" presents original research results on the leading edge of genetics discovery. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. In this continuing series compilation, the authors present and discuss varied topical data such as the "s" allele of the serotonin transporter and its lack of association with major depression in veterans; effects of regular versus special school placement in students with Down Syndrome; the biology of telomeres in multipotential stromal cells; genetic diversity of human and animal papillomaviruses; telomere length in lymphoid malignancies; telomerase and telomere maintenance in the blight fungus ustilago maydis; roles of mirnas in cancers; and genetic programming for music.
