Fig. 8 Induction of gynogenesis by sperm from cea mutant males. (A) Diagram of gynogenesis procedure. (B–E) Side views of 3-day p.f. embryos. For comparison, panels B and C show, respectively, control diploid wild-type and albino pigmented derived from standard natural crosses. (D) albino haploid embryo derived from fertilization of albino females with UV-inactivated wild-type sperm. (E) A fraction of embryos fertilized with UV-inactivated sperm from cea mutant males develops into albino diploid gynogenotes.
