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 ...

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 ...

Genetic drift continues to change the frequency of alleles—different versions, or variants, of a given gene—as it does in all biological populations. "The census size of humans has now ...

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 ...

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 ...

“In humans there is just too much genetic variation, making it hard to identify exactly which genetic mutation causes a specific disease.” Dogs Genetics Daily Newsletter ...

This new study is the first time researchers have carried out a large-scale genetic analysis of S. aureus from samples of human carriers, instead of observing the bacteria in a laboratory setting.

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 ...

They looked at genetic data from the UK Biobank and found that many of the Neanderthal variants in modern humans affect sleep preference. In particular, the tendency to wake up early–or ...
