| Abstract: | The feather pulp cells are cultured for chromosome preparations which are air-dried and stained with Giemsa.Two birds of them are studied for sex identification and karyotype analysis. The results show that, one N. nippon, Xin Xin, is a female(ZW) bird while the other, Yang Yang, is a male(ZZ)one. The total number of chromosomes presents 2n=68, in which there are 10 pairs of maco-chromosomes including a pair of sex chromosomes, and the rest of them are micro-chromosomes. The length of W chromosome is about half of the Z chromosome. |
