The nuclear genomes of most higher eukaryotic organisms are diploid and are characterized by disomic inheritance and sexual reproduction. So, nuclear genes come in allelic pairs that are often subtly ...

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 ...

Retinitis pigmentosa (RP) is an eye condition that can be genetic. In this way, people usually need to inherit two copies of a genetic variation that causes RP, one coming from each parent. RP may ...

Hemophilia is a bleeding disorder that can affect the blood’s ability to clot properly. In most cases, people inherit the gene variations for hemophilia in an X-linked recessive inheritance pattern.

Scientists have unraveled the enigma of inheritance of coat color patterns in dogs. The researchers discovered that a genetic variant responsible for a very light coat in dogs and wolves originated ...
