Table 1. The EndoG mutation is early embryonic lethal.
| EndoG+/+ | EndoG+/- | EndoG-/- | |
|---|---|---|---|
| Postnatal | 113 | 200 | 0 |
| E8.5–14.5 | 16 | 30 | 0 |
| E6.5–7.5 | 18 | 33 | 0 |
| E3.5 | 47 | 54 | 8 |
| E2.5 | 57 | 70 | 9 |
Postnatal mice and E8.5–14.5 embryos were genotyped by Southern blotting and PCR, respectively. E6.5–7.5, E3.5, and E2.5 embryos were genotyped by nested PCR. Number of mice and embryos of each genotype are listed.
