Abstract:
The mitotic chromosomes of the ratlike hamster were studied under light microscope. The observations revealed that chromosome number of this species of genus cricetulus was 2n=28. The autosome pairs 1～11 were acrocentric and progressively decreasing in size, whereas the pairs 12 and 13 were four extremely small submetacentric chromosomes. The sex chromosome pairs were XY and XX for male and female animals respectively The X chromosome (Large subtelocentric) and Y chromosome (Submetacentric of medium size) were easily distinguishable from each other as well as from all autosomes. The poessible use of these outstanding chromosomal characteristics was briefly discussed.
