| mRNA injection | 136 (93)a | 60 | 5 | 1 (20%) | 3 (60%) | 1 (20%) |
| CRISPR-EZ, 1 ms | 140 | 85 | 44 | 23 (53%) | 12 (27%) | 9 (20%) |
| CRISPR-EZ, 3 ms | 120 | 90 | 33 | 1 (3%) | 29 (88%) | 3 (9%) |
a 93 of 136 collected embryos were injected after screening for presence of pronuclei. In contrast, CRISPR-EZ was performed on all collected embryos.
