An analysis of the coding sequence for the Y-chromosome (Homo sapiens) has been performed, embedded in the formalism of κ-statistics, which naturally encompasses long-range correlations. In this formalism, the entropy has been written as a function of κ (called the deformation —or entropic— parameter). The κ-entropy has been linked directly to dimensional parameters defined for the DNA chain associated with the chromosome Y. Our analysis indicates that there are certain regions of chromosome Y which exhibit linearity between entropy and sample sizes for some particular values of κ, implying that, on these regions, the information contained on the DNA increases monotonically linearly with the sample size, and also depicts an internal order.
