Globin gene family evolution
WebA gene family is a set of several similar genes, formed by duplication of a single original gene, and generally with similar biochemical functions.One such family are the genes for human hemoglobin subunits; the ten genes are in two clusters on different chromosomes, called the α-globin and β-globin loci. These two gene clusters are thought to have … WebThe beta-globin gene family located on chromosome 11 is shown in the figure below and consists of five functional genes (blue boxes) and two pseudogenes (diagonal lines). …
