一个广泛提倡的机制， 生殖隔离涉及到 发送者/接收者之间的通信系统。 本研究 将检验雄性鸣唱和雌性交配的假设 偏好在两个兄弟姐妹中是遗传相关的 蟋蟀Allonemobius fasciatus和A.社会。 父母- 将使用后代和全同胞定量遗传学方法 评估种间和种内变异的程度 在男性呼唤歌曲相关的变化，女性 一个男人的呼唤歌曲的偏好。 此外该 雌性择偶偏好的遗传力（用趋声性测量 （歌曲）将被评价。 知识 雌性偏好遗传力及其遗传相关 将提供关于速度的见解 对过去、现在和未来的选择性压力的反应;更多 重要的是，缺乏遗传变异可能会导致 配偶识别进化的基本限制 系统.

A widely advocated mechanism for the evolution of reproductive isolation involves the co-evolution of sender/receiver communication systems between sexes. This study will test the hypothesis that male calling song and female mate preference are genetically correlated in the two sibling ground cricket species, Allonemobius fasciatus and A. socius. Parent- offspring and full sib quantitative genetic methods will be used to assess the degree to which inter-and intraspecific variation in male calling song is correlated to variation in female preference of a male's calling song. In addition, the heritability of female mate preference (as measured by phonotaxis to male calling songs) will be estimated. Knowledge of the heritability of female preference, and its genetic correlation with male calling song will provide insights concerning the speed of response to past, present and future selective pressures; more importantly, the absence of genetic variance could pose a fundamental constraint to the evolution of mate recognition systems.
