Inheritance of acrocentric association patterns.
The individual association frequencies of acrocentric chromosomes identified by fluorescent markers were analyzed in 17 individuals from 3 families. The frequency of association appears to be a characteristic property of an individual chromosome, since certain marker chromosomes showed an increase in frequency of association in each family member in which they appeared. Most of the marker chromosomes with increased frequency of association had a longer nucleolar constriction than their homologs.
