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.
So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by mulitple genes. This information came from my biology textbook, Biology: Principles and Explorations by Holt, Rinehart, and Winston.ultiple alleles are genes that have more than two alleles. An  example of this would be blood types, with ABO as three separate  alleles.   Polygenic traits are traits â¦ whose phenotype rely on alleles from  different genes.
