  • Title: [Heterochromatic regions of human chromosomes 1, 9, 16 and Y and the phenotype].
    Author: Podgol'nikova OA, Grigor'eva NM, Bliumina MG.
    Journal: Genetika; 1984 Mar; 20(3):496-500. PubMed ID: 6232170.
    Abstract:
    The relationship between variability of the heterochromatic regions of chromosomes 1, 9, 16, Y and the anthropometric characteristics (the height, the biacromial diameter and weight) was studied in two groups of children; 70 children had embryopathies of unknown etiology and 40 children had the Down syndrome. The positive statistically significant correlation of the C-segments lengths of chromosomes 1, 9, 16, their sum included, and above characteristics was found. The correlation coefficients of Y-chromosome were non-significant. The problems of functional role of the structural heterochromatin and its influence on viability and physical development of the organism are discussed.
