Allele is the term used to describe these different versions of a gene. For example, at one particular loci, two alleles may exist, ... This combination of genes and gene variants underlies human ...

Genetics is the study of how heritable traits are transmitted from parents to offspring. The theory of natural selection states that variations occur, but Charles Darwin couldn't explain how.

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 ...

The authors found a strong correlation between a nation's happiness and the presence of the A allele in the fatty acid amide hydrolase (FAAH) gene variant rs324420 in its citizens' genetic make-up ...

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.

Genetic crosses of single gene combinations (monohybrid inheritance) can be shown and examined using Punnett squares. These show the possible offspring combinations that could be produced, and the ...

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 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.
