Inheritance of Q and C band polymorphisms.

Sequential Q and C banding of chromosomes from 36 individuals in three unrelated families revealed Q band variants on 6 different chromosomes and C band variants on 14 different chromosomes. These variants were inherited in Mendelian fashion with one excpetion in which a C band variant absent in the parents was found in a child. Although some of the Q band variants were also detected with C banding, there was no consistent correlation between the intensity of variant Q and C bands.
