DECREASE IN FLUCTUATING ASYMMETRY AMONG HOUSE MICE IN TERRITORIES POLLUTED WITH CHEMICAL AND RADIOACTIVE MUTAGENS

The authors evaluated fluctuating asymmetry of the width of parietal b ones, and the lengths of frontal bones, nasal bones, and the incisive foramen in populations of house mouse living at five populated points in the Central Urals with different degrees of technogenic pollution a nd displaying increased frequency of cells with chromosome disorders. As the stressing action intensified, fluctuating asymmetry of the leng ths of frontal and nasal bones decreased, remaining unchanged in the c ase of the other two traits.
