Abstract Adkins-Regan 9514088 The goal of the proposed research is to analyze developmental processes leading to adult mate choice and mate preferences, especially preferences that are sexually dimorphic (different in males and females). The project will focus on a particularly robust and widespread aspect of mate choice, preference for opposite-sex partners (sexual partner preference), and a species well-suited to the goal, the zebra finches treated with estrogen during the first two weeks posthatch and housed in an all-female zebra finches treated with estrogen during the first two weeks posthatch and housed in an all-female environment from 40 days (independence from the parents)to 100 days (young adulthood) then prefer to pair with other females. In order to address important questions raised by this discovery, a series of experiments will be conducted in which annals are exposed to different hormonal or social environment manipulations during development and then tested for sexual partner preference--organizational effects of hormones produce early in development, and sexual imprinting--and will elucidate the manner in which hormonal and experiential influences interact during development. This work will advance our understanding of mate choice and of reproductive behavior development.

摘要Adkins-Regan 9514088该研究的目的是分析导致成人伴侣选择和伴侣偏好的发展过程，尤其是性二态性的偏好（男性和女性不同）。 The project will focus on a particularly robust and widespread aspect of mate choice, preference for opposite-sex partners (sexual partner preference), and a species well-suited to the goal, the zebra finches treated with estrogen during the first two weeks posthatch and housed in an all-female zebra finches treated with estrogen during the first two weeks posthatch and housed in an all-female environment from 40 days (independence from the父母）至100天（成年年轻），然后更喜欢与其他女性配对。 为了解决这一发现提出的重要问题，将进行一系列实验，在开发过程中，年鉴暴露于不同的荷尔蒙或社交环境操作中，然后测试了性伴侣的偏爱 - 激素的组织效应在开发中产生早期的组织效应，并且性别知性会产生性别烙印 - 并将阐明在发展过程中荷尔蒙和实验性影响的方式。 这项工作将促进我们对伴侣选择和生殖行为发展的理解。
