Abstract: The comb type is one of domesticated fowl’s traits, and combs of diffe
rent ckicken breeds have different characteristics and shapes. There are four types in chicken combs: pea comb, rose comb, single comb and walnut comb. The comb morphology of chickens is determined by the rose comb gene(R) and the pea comb gene(P),but they are on different chromosomes. This article reviews the relationship between comb genes and performance,as well as heredity rule of comb types and the mapping of comb gene in the chicken.

Key words: chicken; comb type; gene mapping; performance
