Older adults are most likely to develop shingles, which is why the shingles vaccine is recommended for people age 60 and older. Zostavax is currently the only vaccine approved by the Food and Drug Administration (FDA) to prevent shingles.
Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals.
Examples of human polygenic inheritance are height, skin colour and weight. Polygenes allow a wide range of physical traits. For instance, height is regulated by several genes so that there will be a wide range of heights in a population. Word origin: poly = many + genic = of genes. See also: polygene, inheritance, phenotype. Please contribute to this project, if you have more information about this term feel free to edit this page.
