Imagine your doctor calls you to discuss the results of your genetic testing. They tell you your results indicate you are ...

Genetic variation within a population is measured according to the number of different alleles of all genes and the frequency with which they appear. Variation is high when there are many ...

Although Mendel's principle of independent assortment states that alleles of different genes will segregate independently into gametes, in reality, this is not always the case. Sometimes ...

They thus pared down the 613 genetic variants in the region first to 20 variants that impacted gene expression, and then to four that showed activity differences between the introgressed and ...

Each gene might have different forms, and these are called alleles. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and genes.

Some characteristics are controlled by a single gene, such as fur colour in animals and red-green colour blindness in humans. However, most characteristics are caused by the interaction of many ...

Have you ever wondered why some people cannot stand bitter foods like kale, broccoli, black coffee or dark chocolate, while ...

This gene makes people sensitive to some bitter chemicals, such as phenylthiocarbamide (PTC) and propylthiouracil (PROP).

A group of scientists has found clues in blood groups that explain how modern humans managed to survive and expand from ...

Scientists uncovered how ancient blood groups helped Homo sapiens as compared to Neanderthals in their survival and spread ...

The number of genes and alleles linked to variations in phenotypes, after refining our data analysis to include only ...

Mayo Clinic researchers found that a gene variant, the TPMT∗8 allele ... "Genotyping will only detect the alleles that are targeted by a test. Some laboratories, including ours, are moving ...
