a
Embryos at early stage 11 were stained with anti-Vasa antibody. PGCs left in the middle of the embryo were counted.
b
Probabilities were calculated by Fisher's exact probability test. Probabilities were compared (from top to bottom): hmgcr26.31 with hmgcr26.31/TM3, abdA46.51 with abdA46.51/TM3, sli2 with sli2/CyO, NetA,B with NetA,B/FM7, and sim2 with sim2/TM3.
