The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

If PKU carriers were most likely to have children than non-carriers because of the protective effects of the PKU gene, over time, the disease-causing allele would increase the population.

EvolGenius is a two-locus population genetics simulation written for use ... This includes which allele (if either) is fixed; the allele and gene copy fixation times; the final frequencies of ...

The researchers then compared the relative gene expression levels of each allele across different tissues within each ... “It’s not founded on well-established concepts, such as imprinting, ...

A study conducted by a research team at the Crick Institute identified important genes on the Y chromosome that regulate ...

Researchers have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't produce enough ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspid aortic valve disease.

Macquarie University researchers have worked with an international team of scientists to achieve a major milestone in synthetic biology by completing the creation of the final chromosome in the ...

Robert Feil, Institute of Molecular Genetics, Montpellier-CNRS “What’s unusual here ... The results indicate that male mice’s foraging behavior was altered when they lost the maternal allele of either ...

Researchers say study represents a resource that could also help to dissect Y-gene functions in other tissues.
