When genetic load is determined primarily by recessive mutations, interactions between the mating system and inbreeding depression should lead to one of two evolutionary stable endpoints: predominant outcrossing associated with strong inbreeding depression or predominant self-fertilization with weak inbreeding depression (Lloyd 1979; Lande and Schemske 1985; D.
Because of an uncontrolled fertilization occurring in the blank control, further experiments were carried out to examine if this resulted from self-fertilization or contamination.

is] are positive (Table 2), as would be expected given that the hermaphrodites are known to be capable of self-fertilization (Jolls and Chenier 1989; Petersson 1992).
In some species, such as Halocynthia roretzi and Ciona intestinalis, a self-incompatibility mechanism is in place to avoid self-fertilization (autologous fertilization) (Morgan, 1944; Rosati and de Santis, 1978; Fuke and Numakunai, 1982).
