The genetic basis of variation in gene expression lends itself to investigation by microarrays. For genetic analysis, we view the expression level of a gene as a quantitative or 'complex' trait ...

Moreover, complex regions of genetic variation are not particularly well understood outside of humans because nonhuman primate genomes have not been finished to the same standard as the human ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop.

University of Michigan researchers have developed a statistical method that can be used for such wide-ranging applications as tracing your ancestry, modeling disease spread and studying how ...

All humans have APOE protein in their genetic makeup, and the main forms, called alleles, are ε2, ε3 or ε4. Each person inherits two APOE alleles—one from each parent—resulting in one of ...

Modern humans left Africa some 60,000 years ago in the event known as "Out-of-Africa." In Asia, they coincided with the Denisovans, and that encounter may have led to confrontations and ...

Pitting on Paranthropus robustus teeth. Ian Towle, Author provided. Genetic conditions are rarely identified in the fossil record for several reasons. Once we get past 50,000 years or so ago, it ...

Human DNA also points to Africa. Living Africans have a vast amount of genetic diversity compared with other people. That’s because humans lived and evolved in Africa for thousands of ...
