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 ...

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

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 ...

Specifically, they found on further experimentation that three of the four introgressed alleles significantly altered the expression of CCR1 and CCR5, genes that code for key receptors involved in ...

An international research team has discovered various mechanisms in asexual mites that generate genetic diversity and thus ...

Since these alleles have been around for more than 5000 years, they may in fact have some evolutionary advantage. “Common [gene] variants have subtle roles across the genome, affecting multiple ...

Ben and Tom are identical twins. This means they have the exact same genes and alleles. Ben and Tom both have blue eyes, but they are different heights. Explain both of these observations.

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

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

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 ...

Although many of the genes involved in cancer have now been identified, a major challenge is discovering which specific alleles of these genes are involved and how these alleles modulate therapeutic ...
