Study of the germ cell migration to the gonad buds of quail embryo after the action of 2,4,5-trichlorophenoxyacetic acid]

At stages 16 and 18, the germ cells counts, in the quail embryos' gonads from control and 2,4,5-T treated eggs, show no significative difference. On the contrary, at stage 20, the gonocyte numbers of the treated embryos are strongly decreased. Actually, this mechanism cannot be stage precisely.
