Induction of gynogenesis in endangered sarpunti, Puntius sarana (Hamilton) and evidence for female homogamety
The experiment was conducted to optimize a procedure of gynogenesis induction in Puntius sarana by suppressing meiotic cell division in fertilized eggs. Gynogenesis was induced by fertilizing normal eggs with genetically inactivated sperm followed by heat shocking. The sperm were inactivated by expo...

Seven different heat shock temperatures viz., 32, 34, 36, 38, 39, 40 and 41 °C were tested for different lengths of time to find out the best combination of heat shock temperature and shock duration. Exposure of inseminated eggs to heat shock at 39 °C for 2–4 min after fertilization increased the yield of diploid gynogenetic offspring. Early developmental stages of
