Abstract
Indian Muntiacus muntjac G-banded chromosomes were used for computerized analysis for standardized karyotype generation. Individual chromosomes on high-contrast photographic negatives were scanned densitometrically. Alignment of each chromosome for analysis was achieved by locating predominant peaks as well as the centromere. This provided better alignment than the use of the chromosome-end locations. The standardized set was obtained by determining the root-mean-square average density along 10–20 homologous chromosomes. The resulting standard karyotype differs from those published earlier. Prophase chromosomes exhibited greater detail than more condensed metaphase chromosomes. Although Indian muntjac chromosomes were used as a model, the method of analysis should be readily adaptable for examining chromosomes of any origin. The analytic technique should be within the capabilities of the smallest cytogenetic laboratories.
