title: The quantitative analysis of polymorphism on human chromosomes 1, 9, 16, and Y. III. Study of relationships of C segments' lengths in individual karyotypes.
abstract: The correlation relationship of the lengths of C segments on chromosomes 1, 9, 16, and Y was studied in a group of normal boys and girls (50 boys and 50 girls). No correlation was found between the C segment lengths, either on homologs or on chromosomes of various pairs. This confirms the idea of random combinations of the said chromosomes with C segments of different lengths in an individual karyotype.
