[Segregation of Q-polymorphic variants of human chromosomes].

The inheritance of Q-band polymorphism has been investigated in 15 families from 2 villages of the Uzbek SSR on six pairs of chromosomes (3, 13, 14, 15, 21 and 22th). Q-band polymorphism appears to segregate in a Mendelian manner. No Q-bands arisen de novo were found in this population. There is some evidence to suggest a preferential segregation of brilliant Q-band polymorphism but it may be an artifact caused by insufficient data and scoring error.
