Comparison of G-, Q-, and EM-Banding Patterns Exhibited by the Chromosome Complement of the Indian Muntjac, Muntiacus muntjak, with Reference to Nuclear DNA Content and Chromatin Ultrastructure.

摘要

The Indian muntjac has the lowest chromosome complement of any mammal known to date, with 2n=6 in the female and 2n=7 in the male (Wurster and Benirschke, 1970). It also exhibits chromosomes wherein each homologue is readily distinguishable from the next. As first observed in the study by Wurster and Benirschke, the karyotype of the male muntjac exhibits two large metacentrics, three smaller acrocentric, a large acrocentric having the 'X' chromosome connected to it by a long giraffe-like neck, and a small metacentric, the 'Y'. There is never any question as to which chromosome is being observed, even in the electron microscope. (Author)
