Abstract
Dwarf gene plays an important role in the poultry development. Much has been known for the regulation of sex-linkage dwarf genes, less information is available about the autosmal dwarf genes. Xingyi bantam is an endangered native breed in Guizhou, which shows different characters from sex-linkage dwarf genes about pygmy and tall foot separation, Early embryonic regularity death. In this study, we examined rare phenomenon mentioned above through establishing pedigree. The ratio of pygmy foot individuals to tall foot individuals was 2:1 (X2 P=0.05) in Xingyi bantam pedigree, which is different from the classical ratio 3:1 of Mendel. The autocopuation (selfing) offspring of tall foot individuals were tall foot. Those results suggest that the pygmy character of Xingyi bantam is in control of Cp-cp, a pair alleles located autosomal. The pygmy foot is the dominant character to high foot, but the dominant homozygote is death. In addition, we preliminarily determined MORF4L1 was the major genes of Cp through candidate genes method. These findings may provide some insight regarding harmful genes knockout for the improved breeding of Xingyi bantam.
