ABSTRACT
Spontaneous and high temperature-induced crossing over in regions b-cn and cn-vg of chromosome 2 was studied in Drosophila stocks and hybrids differing in fertility level and heat resistance. No essential distinction in recombination frequency was revealed in variants studied under the temperature 21-22 degrees C. The effect of temperature on 1- and 10-days imago during 4 or 7 h under 35 degrees C leads to increase in exchange frequency in the region b-cn. The hybrids show weaker reaction to this influence.
