Abstract:The segregations of body color and scale type in progenies derived from selfing and intercross among Yellow Carp(Cyprinus carpio),Blue Carp and Red Carp populations were analyzed.The results showed that the body color and scale type were homozygous in red parents,but heterozygous in yellow parents.In blue parent carps,body color was homozygous,while scale type was heterozygous.Complex and diverse phenotypes of body color in progenies from different cross combinations were observed,such as bluish gray,white,bluish yellow and blue white,in addition to red,yellow and blue.Some red individuals with black on back were also observed.Moreover,the distribution of chromatophores in scales and fin rays were described,and the inheritance characters of body color in carp crosses were analyzed and discussed in this study.
