研究了基因-文化协同进化的单倍性双基因座模型，在该模型中，受自然选择影响的二分性表型是垂直传递的，概率取决于所选择的亲本的基因和表型以及后代的基因。得到了遗传单纯角平衡点的稳定性条件。在这个一般模型的专门化中，一个轨迹控制自适应信息的传输，而另一个轨迹控制自适应信息的接收。充分分析了这种双协进化模型的边角均衡，从垂直传输的效率、拥有信息所获得的选择优势、传输和接收的成本以及两个点之间的重组比例等方面推导了传输和接收协同进化的条件。该模型的可能应用是研究长尾猴的语义警报叫声的进化，以及人类语言的语音方面。在具有二倍体遗传学的第三个模型中，我们考虑了从突变-选择平衡开始的文化传播的增加，在该平衡中，适应性表型是一个座位上显性基因的结果。第二个基因以这样一种方式控制表型的传递，即第二个基因上的新突变体允许从具有适应性表型的父母那里学习适应性表型。这种新的突变体在罕见的情况下不能增加。
A haploid sexual two-locus model of gene-culture coevolution is examined, in which a dichotomous phenotype subject to natural selection is transmitted vertically with probabilities dependent on the chosen parent's genotype and phenotype and the offspring's genotype. Stability conditions for the genetically monomorphic corner equilibria are obtained. In a specialization of this general model, one locus controls the transmission and the other controls the reception of adaptive information. The corner and edge equilibria of this doubly coevolutionary model are fully analyzed, and conditions for transmission and reception to coevolve are derived in terms of the efficiency of vertical transmission, the selective advantage gained from possessing the information, the costs of transmission and reception, and the recombination fraction between the two loci. Possible applications of the model are to the evolution of semantic alarm calls in vervet monkeys and the phonetic aspects of human language. In a third model with diploid genetics, we consider the initial increase of cultural transmission from a mutation-selection balance in which the adaptive phenotype is the consequence of a dominant gene at one locus. A second gene controls the transmission of the phenotype in such a way that a new mutant at this second locus permits learning of the adaptive phenotype from a parent who has it. This new mutant cannot increase when rare.
