Abstract:
Genetic variability was analysed in two common breeds of pheasant (Phasianus colchicus L. 1758) by means of cross-species amplifications of microsatellite loci: 154 chicken, Gallus gallus and 32 turkey, Meleagris gallopavo, primers were tested for amplification of pheasant DNA. Thirty-six primers (25 specific for chicken and 11 for turkey) amplified pheasant DNA. Fifteen markers yielded specific products and were tested for polymorphism. Eight of them (55%) were polymorphic, with an average polymorphism of two alleles per locus. Specific polymerase chain reaction (PCR) products were sequenced; repeats were found in 11 of the 15 markers, although only two loci showed the same repeat and could be homologous to chicken ones.
