Comparative Studies on SC karyotypes of Chrysolophus amherstiae,C.pictus,Phasianus colchicus

Abstract: Micro-spread and silver-stained preparations of spermatocytes of C.amherstiae,C.pictus and P.colchicus have been analyzed by electron microscopy.SC karyotypes of three pheasants are very similar and are 2n=82,ZZ/ZW sex ditermined and male is ZZ.No.1 and Z-SC are metacentric,the others are telocentric.Relative length of Z-SCs has strikingly difference among spermatocytes,but the mean is always between No.3 and No4.SC.The main difference of SC karyotypes of three pheasants is the length of corresponding SCs.The consanguinity and probable position of three pheasants in evolution have been discussed.Large centrioles are tound for the first time in C.amherstiae and C.pictus spermatocytes and can be analyzed at the same time in SC samples prepared by microspreading technique.
