Geographic Variation in the Sex Chromosomes of the West Malaysian House Shrew Suncus Murinus (Insectivora, Soricidae)
Three males and two females of the West Malaysian house shrew, Suncus murinus (Linnaeus), collected from Malacca appeared to be monomorphic. All individuals had 2n=40 comprising 12 pairs acrocentric, 4 pairs meta-/submeta-centric and 3 pairs subacrocentric autosomes, and meta/submeta-centric X and s...

| Summary: | Three males and two females of the West Malaysian house shrew, Suncus murinus (Linnaeus), collected from Malacca appeared to be monomorphic. All individuals had 2n=40 comprising 12 pairs acrocentric, 4 pairs meta-/submeta-centric and 3 pairs subacrocentric autosomes, and meta/submeta-centric X and submetacentric Y sex chromosomes. The autosome complement and the duplicate type X chromosome were similar to those with 2 n = 40 reported previously in West Malaysia. The Y chromosome, however, was larger and also differed in its morphology viz. submetacentric instead of metacentric. The West Malaysian taxon was compared with the taxa reported in India. Japan and South Vietnam, and the geographic variations discussed. |
