الملخص EN

White mice, Balb \ C males and females, were exposed to rodenticide zinc phosphide , The frequency of aberrations in metaphase 1 chromosome recovered from oocytes was compared with those recovered from spermatocytes T in pachytene and diplotene phases .

The results revealed that: - 1.

Was not affected in oocytes and spermatocytes in 1 and 7 days after treatment, but it was effected in 21 and35 days after treatment.

2.

The frequency of aberrations in oocytes did not different from spermatocytes during diplotene t but significatly more chromosome aberrations were found in pachytene phase compared with those in diplotene phase.

3, Increase chromosome aberration especially after 21,35 days .

4, It was pachytene more sensitive !o rodenlicide than diplotene phase.
