Abstract:
Studies have been carried out on carp gynogenetic offspring by four autosome genes: Tf (transferrin), Est(s) (muscle esterases, slow), Est(f) (muscle esterases, fast), My (myogenes). Homozygosity and phenotypical homogeneity by all the loci studied are established for carps of the second generation of the induced gynogenesis. In the first generation obtained from heterozygous females, the correlation of homozygous offspring of two classes corresponding to the theoretically expected one (1:1). Heterozygous offspring makes (%): 5.0 (Tf), 9.1 (Est (s)), 28.4 (Est (f)). Three loci are mapped in relation to the centromere by heterozygote frequency. Genetic inactivation of the radiated sperm has been confirmed using biochemical markers. Due to the codominant nature of inheritance and high polymorphism, protein loci are considered to be convenuent genetic markers.
