Normal numbers of male and female gametocytes are produced. Male and female gamete formation is normal(escape from host red blood cell, formation of 8 motile male gametes). Female gametes are strongly affected in their fertility, resulting in nearly complete inhibition of ookinete formation in vitro (>0.99%). Motile males fail to attach to and penetrate female gametes.Mutant male gametes are fertile as shown by cross-fertilisation with wild type female gametes.
