Segregation and mapping of allozymes of the apple maggot fly

The genetics of electrophoretic enzyme variants (allozymes) of 11 enzymes of the apple maggot, Rhagoletis pomonella, has been investigated by single-pair crosses. All allozymes segregated as simple Mendelian genes. Null alleles occur at two enzymes--phosphoglucomutase and alcohol dehydrogenase. Five linkage groups have been established.
