The Latin name sorbus was borrowed into Old English as syrfe. The name service-tree for Sorbus domestica is derived from that name by folk etymology.
Restriction fragment length polymorphism. In molecular biology, restriction fragment length polymorphism, or RFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules from differing locations of restriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated.
