群体之间基因流动的动态最终取决于个体之间的行为相互作用（Ritchie，2007），从最广泛的意义上解释为包括植物和微生物中的化学和机械相互作用。因此，配偶选择的机制可以决定杂交是促进还是阻碍物种形成。此外，交配决策背后的过程的性质对它们作为选择代理的作用施加了重要的限制。了解杂交的进化遗传学需要更详细地考虑决定个体之间交配相互作用的因素。为了使杂交产生显着的进化后果，必须发生两件事：首先，交配必须发生在来自不同种群的雄性和雌性之间；其次，杂种必须彼此交配和/或与亲本回交。越来越多的证据表明，种间交配的行为障碍很脆弱，并且容易受到环境扰动的影响。一旦杂交发生，新的信号组和新的偏好组可以促进与亲本的回交，或者可以导致杂交物种形成。我将依次讨论每个过程。
The dynamics of gene flow among populations ultimately depend on behavioural interactions among individuals (Ritchie, 2007), construed in the broadest sense to encompass chemical and mechanical interactions in plants and microorganisms. The mechanisms underlying mate choice can, therefore, determine whether hybridization promotes or retards speciation. Further, the nature of the processes underlying mating decisions imposes important constraints on their role as agents of selection. Understanding the evolutionary genetics of hybridization requires a more detailed consideration of what determines mating interactions among individuals. For hybridization to have notable evolutionary consequences, two things have to happen: first, matings have to occur between males and females from divergent populations and second, hybrids have to mate with each other and/or backcross to parentals. There is a growing body of evidence to suggest that behavioural barriers to interspecific mating are brittle and susceptible to environmental perturbation. Once hybridization occurs, novel suites of signals and novel suites of preferences can facilitate backcrossing to parentals or, alternatively, can lead to hybrid speciation. I will discuss each of these processes in turn.
