Dr. Sushil Neupane's notes on "Introductory Genetics and Animal Breeding" for the 2nd year, 1st semester of the Diploma in Animal Science (latest syllabus of CTEVT) provide a comprehensive overview of key concepts and principles related to genetics and animal breeding. The notes cover fundamental topics in genetics and their practical applications in livestock production and breeding programs.

meat animals.

12. They are multi colored.
Polish are a very special and unique breed of
chicken with their huge bouffant crest of feathers
and v-shaped comb.
Polish are sweet, beautiful exhibition birds and can

They are tame but their behavior can be a bit
wacky since their crest limits their vision.
