    Widely Applicable PCR Markers for Sex Identification in Birds

    To aid in avian sex determination if birds are not sexually dimorphic and/or they are sexually immature, several molecular assays involving the polymerase chain reaction (PCR) have been developed. To test in a...

    Karyotypic evolution of a novel cervid satellite DNA family isolated by microdissection from the Indian muntjac Y-chromosome

    A minilibrary was constructed from DOP-PCR products using microdissected Y-chromosomes of Indian muntjac as DNA templates. Two microclones designated as IM-Y4-52 and IM-Y5-7 were obtained from negative screeni...

    Comparison of theα-globin gene cluster structure in Perissodactyla

    To investigate molecular evolution in a mammalian order with a comprehensive fossil record, we have constructedα-globin-like gene cluster maps for members of the order Perissodactyla. Although the arrangement of ...

    Distribution of silver-stained nucleolus-organizing regions in the chromosomes of the Equidae

    The distribution of silver-stained nucleolus-organizing regions (NORs) in fibroblast chromosomes from all seven extant species of Equidae are described. There are variations in the number and locations of silv...
