摘要：
Number and characteristics of chromosomes of the giant freshwater prawn, Macrobrachium rosenbergii, were studied from the second meiotic metaphase of the fertilized egg (n = 59), from mitotic metaphase of the actively dividing embryonic cell and from spermatogonial metaphase of the testicular tissue (2n = 118). The karyotype consistes of 6 large, 26 medium, 15 small and 12 very small pairs. Most of these chromosomes are submetacentric and metacentric. Only 6 pairs appear to be either telocentric or acrocentric in configuration.
