分析和数值模型来研究配子遇到不同大小的配子之间的2和3个维度，而不假设预先存在的交配类型进行描述。如果配子囊产生不同大小的配子，同花受精的种群可以被它成功地侵入。存在一个低的自适应峰值为isogamy和一个更高的自适应峰值为anisogamy表明，随机力可能是最初重要的驱动isogamy通过健身鞍anisogamy。
Analytical and numerical models to study gamete encounters in 2 and 3 dimensions between differently sized gametes without assuming pre-existing mating types are described. An isogamous population can be successfully invaded by a gametangium if it produces gametes of a different size. The existence of a low adaptive peak for isogamy and a much higher adaptive peak for anisogamy suggests that stochastic forces may be initially important in driving isogamy through the fitness saddle to anisogamy.
