When you see a dominant trait, the underlying genetic make-up can still be ambiguous. See how researchers use test crosses to find out the genotype behind the phenotype. The test cross is another ...

"Hepatitis" means inflamed liver. The virus known as hepatitis C, or hep C, is the most common cause. Scientists call the different types of hepatitis c “genotypes.” Each hepatitis C genotype has a ...

Background. We aimed to investigate the characteristics of hepatitis B virus (HBV) genotype C subgroups in Hong Kong and their relationship with HBV genotype C in other parts of Asia. Methods.

Multiple genetic loci have been convincingly associated with the risk of type 2 diabetes mellitus. We tested the hypothesis that knowledge of these loci allows better prediction of risk than knowledge ...
