Frequency of axis duplication by ventral injection of Axil and Xwnt8 mRNAa
| mRNA and region | No. of embryos with phenotype
|
No. of dead | No. of speci- mens | % of specimens with axis duplication | |
|---|---|---|---|---|---|
| Normal | Axis dupli- cation | ||||
| Xwnt8: ventral blastomere | 18 | 30 | 1 | 49 | 61.2 |
| Axil + Xwnt8: ventral blastomere | 36 | 11 | 1 | 48 | 22.9 |
All mRNAs were injected into the subequatorial region of two ventral blastomeres of four-cell embryos.
