Principles for the Buffering of Genetic Variation
Science, 2001Most genetic research has used inbred organisms and has not explored the complexity of natural genetic variation present in outbred populations. The translation of genotype to phenotype is complicated by gene interactions observed as epistasis, canalization, robustness, or buffering.

Serotonin Transporter Genetic Variation and the Response of the Human Amygdala
Science, 2002A functional polymorphism in the promoter region of the human serotonin transporter gene (SLC6A4) has been associated with several dimensions of neuroticism and psychopathology, especially anxiety traits, but the predictive value of this genotype against

Publisher Summary This chapter focuses on genetic variability and its applications in entomology. Without change, genome would be passed identically to future generations. But it would also constrain potential future adaptation to new situations. Only when genetic variability is present processes such as selection, genetic drift, and migration can act

Molecular genetics of antigenic variation
Immunology Today, 1991Antigenic variation is one of the most effective strategies developed by parasites to escape immune destruction. It requires a large wardrobe of surface coats and mechanisms to exchange one coat for an unrelated one. The molecular principles of antigenic variation are now largely known in the bacterial species Borrelia and Neisseria and in the protozoa

What processes account for the remarkable variation in form and function that we see in the living world and how might they be similar or different between microorganisms and macroorganisms? Because natural variation provides the raw material on which evolution acts, this chapter sets the stage for later comparisons in the book.

The Capacity for Genetic Variation
1981The interspecific variation in form in tropical pasture plants (see Figures 3.1–3.14) may cause culture shock to the scientist accustomed to the short, dense leafy swards of temperate climates. The cultivated tropical pasture legumes include trees such as Leucaena leucocephala, twining plants such as Centrosema pubescens capable of climbing 15 m up a ...

Genetic Variation and Diseases
2008This chapter focuses on bioinformatics aspects of genetic variation research. Because of the diversity of this field, an extensive discussion is provided of the issues involved. The status of genetic variation research is discussed, on the basis of the genotype-to-phenotype relationship.
