DNA makes RNA, RNA makes protein, protein makes phenotype—was the guiding framework for understanding inheritance and disease ...

For the past century, Mendelian and multifactorial traits have existed at opposite ends of the disease spectrum in humans. Furthermore, the recent emphasis on genome-wide association studies for ...

The consistent expression of Mendelian traits in both mice and humans is the exception rather than the rule. Many biological aspects of a trait can vary and for different reasons. However, one ...

Facial traits vary among humans, but do tend to group by population. For example, in general, West Africans have wider faces than Europeans and Europeans have longer faces than West Africans.

Human genetic variation recent, varies among populations Date: November 28, 2012 Source: Baylor College of Medicine Summary: ... (A Mendelian trait is controlled by a single gene.

Monozygotic (identical) twins are not always concordant for tongue-curling ability [1], thus, if there is a genetic component, it’s clearly not Mendelian, in other words, it’s not a trait ...

For humans, the trait is vestigial, but since we still need muscles for our ears (called auriculars) and they are part of our facial/head musculature, the trait is unlikely to disappear completely ...

Ethical concerns aside, the genetic ingredients for human traits are so complex that editing a few embryonic genes is unlikely to have much effect — or achieve the fantasy of enhancing humans.
