In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Several genes with varying inheritance patterns are involved in determining your blood type. The most significant gene is the ABO gene which determines your ABO blood type. Like many of your physical ...

Molecular testing, or molecular diagnostics, refers to a group of tests that look at the genetic material in a specimen. It can detect genetic risk factors for certain diseases or provide evidence of ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

Most cases of immunoglobulin A (IgA) nephropathy are sporadic (or idiopathic), occurring over time for reasons experts don't fully understand. Research suggests that genetic factors are involved in ...
