- Аннотация: Viable prelarvae were obtained for the first time as a result of insemination of eggs of the Kaluga Acipenser dauricus with UV-inactivated sperm of the sterlet A. ruthenus. These normally developed prelarvae without any signs of the haploid syndrome carried two maternal alleles at each examined microsatellite locus; they did not have sterlet paternal alleles. The viability of haploid gynogenetic prelarvae is explained by the low level of diploidization of the kaluga genome, which is confirmed by the presence of multivalent configurations (mainly quadrivalents) in prophase I of meiosis in kaluga (with ~260 chromosomes). The results correspond to the extremely low rate of molecular and chromosomal evolution noted for all sturgeons.
