Genotoxic effects of two wildly used rodenticides in Iraq (Zinc phosphate and Brodifacoum) were administered in to the Balbc and wildtype mice, by using sperm head abnormality and reproductive activity.The results showed that the rodenticides have the ability to induce sperm head abnormalities at equal rate in both Balbc and wildtype mice. Also these rodenticides showed a reduction in the individual of both sexes which might lead to a dominant lethal mutation
(Embryo mortality no zygotes) in both Balbc and wildtype .
