The present paper reports the utilisation of gynogenesis in genetic analysis and chromosome mapping in carp. A new colour mutant was analysed with the help of gynogenetic haploid, diploid and biparental F,1 and F2 populations. The mutant character was controlled by two genes, P and R, and only fish with double recessive alleles pprr showed the mutant coloration. The gene- kinetochore (G-K) distances of the genes were established. G-K distances were measured for two other genes—transferrin and scaliness.
