在不同处理条件下，雄性大叶藻与同种雌性的授精率和受精率均显著高于雌性。尽管如此，对同种雌性的偏好并不是排他性的，因为有20%到50%的异种雌性受精。男性之间的社会互动可能最好地解释了这一结果，因此可能在维持单性恋和双性恋的交配关系中起着重要作用。(C) 2011年《鱼类生物学作者杂志》(C) 2011年《不列颠群岛渔业学会》
Male sailfin mollies Poecilia latipinna were tested in five different treatments that varied in the relative frequency of heterospecific gynogens (Amazon molly Poecilia formosa) to conspecific females to determine whether social interactions among males within a population causes some males to mate with heterospecific females. Male P. latipinna inseminated a significantly higher proportion of conspecific females and fertilized a significantly higher number of conspecific eggs regardless of the treatment. Nonetheless, preference for conspecific females was not exclusive as a range of 20 to 50% of heterospecific females were fertilized. Social interactions among males may best explain the results and may therefore play an important role in the maintenance of unisexual-bisexual mating complexes.
