证据来自对马猕猴桃变种的研究。怀特岛本布里奇的 mesembryanthemum，这表明孵化的幼虫并不代表来自自由生活的幼虫池的随机样本。实验室里的家长不会接受将幼体放在口腔盘上。因此，马甲不太可能成为养父母。酯酶杂合子父母只含有杂合子幼体。有性生殖不能解释这一观察结果，除非父母选择它的后代。由于马匹可以区分自身和非自身，并且幼体可以无性繁殖，因此考虑了受精-选择-克隆繁殖理论，该理论可以解释其他相互矛盾的证据。
Evidence is presented from a study of Actinia equina var. mesembryanthemum at Bembridge, Isle of Wight, which suggests that brooded young do not represent a random sample from a free-living larval pool. Parents in the laboratory will not accept juveniles placed on their oral disc. A. equina are, therefore, unlikely to be adoptive parents. Esterase heterozygote parents contain only heterozygote young. Sexual reproduction cannot account for this observation unless a parent selects its brood. As A. equina can distinguish self from non-self and juveniles may reproduce asexually, a fertilization - selection - cloning theory of reproduction is considered which could account for what is otherwise a conflicting body of evidence.
