Genes and alleles are essential to basic genetics, but what are the differences between them? In this guide, we compare genes and alleles and provide simple definitions and examples for both.<br /> ...

Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population. Usually it is expressed as a proportion or a percentage. In population genetics, allele ...

Sweet potatoes are an agricultural powerhouse that feeds millions globally. However, their complex genetics make it challenging for breeders to understand and improve traits like yield, disease ...

In 34,000 of these regions, genetic variations (SNPs) correlate with the methylation patterns, confirming allele-specific methylation and indicating the extent of genetic influence on DNA methylation.

A chart shows the dominant and recessive traits inherited in successive generations of guinea pigs. (Image credit: Public domain) Genetics is the study of how heritable traits are transmitted from ...

The citizens of nations that rate themselves happiest display a specific genetic feature: their DNA is more likely to contain a specific allele involved in sensory pleasure and pain reduction, say ...

A mutated allele can cause genetic conditions. That’s because the mutation alters how DNA is expressed. Depending on the condition, the mutated allele might be dominant or recessive.

Similar to the human eyes, nose, and lips, the earlobes also have special features.

A genetic allele that affects the body’s response to codeine and antidepressants, for example, “is found in 9%, 17%, and 34% of the Ethiopian, Tanzanian, and Zimbabwean populations, respectively.

The study appears in the May issue of the journal Molecular Biology and Evolution. The ‘9-repeat allele’ genetic marker The team’s work follows up on earlier studies by several of its members who ...

Genetic disorders are lifelong conditions. For this reason, treatments tend to focus on helping a person manage the symptoms, preventing complications, and improving quality of life.
