Abstract
This study showed that increase in temperature resulted in high degree of desynapsis, while at low temperature the expression of desynaptic gene was low. The number of chiasmata per cell and per bivalent at higher temperature is less as compared to low temperature. With the increase of temperature, the number of ring shaped bivalents decreased, while that of rod shaped bivalents increased. The reverse was true with low temperatures. At high temperatures, the terminalization of chiasma apparently occurs at faster rate than at low temperature.
