INHERITANCE OF RAPD MOLECULAR MAKERS IN LAKE TROUT SALVELINUS-NAMAYCUSH

Inheritance patterns of randomly amplified polymorphic DNA (RAPD) phen otypes were tested in 13 full-sib families of lake trout Salvelinus na maycush. Single-pair matings of parents with known phenotypes were mad e, and up to 20 progeny of each mating were used to test inheritance p atterns. Seven RAPD primers amplified 13 polymorphic bands. With the e xception of one family, expected segregation ratios for dominant Mende lian genetic traits were observed. Our results support previously repo rted findings that RAPD markers can be considered Mendelian traits and therefore could be used for analysis of genetic population structure.
