Optimization of DNA extraction from feathers for PCR-based avian sexing test

DNA extraction is a technique used to isolate DNA. Many avian species are monomorphic and this causes difficulty in breeding avian species for bird breeders due to unsuccessful breading. DNA extraction is a crucial part in molecular sexing thus a reliable technique should be developed. Although seve...
