Many familiar citrus fruits have complex hybrid origins. Genetic analysis shows that grapefruit arose from a cross between pomelo and sweet orange, while the histories of different grapefruit cultivars may involve independent crosses. Citrus is therefore a striking example of hybridization in cultivated fruit crops, but this does not mean that most new hybrids across all plants are made from citrus. [1, 2]
