ABSTRACT. Ide spermatozoa were genetically inactivated using ultraviolet (UV) irradiation. The highest survival of haploid embryos was noted in the group treated with UV for 5 min (dose 1920 J m-2). High-temperature shock influenced the suppression of the second polar body in ide oocytes. The highest survival rate of diploid gynogenotes (below 10%) was observed in groups shocked at 12 min after egg insemination for 3 min. Eggs shocked later in time exhibited lower survival rates.
