The mutagenicity of seed powder and seed oil of transgenic CryIA cotton to mammals and fish was evaluated in this study. The raw cotton seed powder or seed oil was mixed into mice and fish's diet. Cyclophosphamide and NaF were used as positive controls respectively. Regular cotton seed powder and seed oil were used as negative controls. The micronucleus frequency in mice bone marrow polychromatic erythrocytes and in eripheral erythrocytes of Zebrafish were assayed in this study. The sperm malformation rate in mice was also investigated.
