This project seeks to understand the development of the vertebrate visual system using genetic analysis. By producing mutations via insertional DNA techniques we will be able to identify genes responsible for normal visual development in a vertebrate. We will insert DNA into the germline of fish species that: (1) have a short generation time; (2) can be scored rapidly for recessive mutations by artificial parthenogenesis; (3) can be cloned; and (4) are easily scored for visual defects. Some of the insertions will cause changes in the normal development of the visual system. Some of these changes should provide basic insights into this complex process. We will use anatomy, physiology, and biochemistry to analyze these mutants. We will apply a host of modern molecular biological techniques to identify and characterize the genes, the function of which is known from their phenotypes.

这个项目试图了解脊椎动物视觉的发展 使用遗传分析的系统。通过插入DNA产生突变 我们将能够识别与正常视觉有关的基因 脊椎动物的发育。 我们将把DNA注入到鱼类的种系中：(1)有一个 世代时间短；(2)隐性突变可快速评分 通过人工孤雌生殖；(3)可以克隆；(4)容易 为视觉缺陷打分。某些插入操作将导致 视觉系统的正常发育。其中一些变化应该 提供对这一复杂过程的基本见解。 我们将使用解剖学、生理学和生物化学来分析这些 变种人。我们将应用一系列现代分子生物学技术来 识别和表征基因，其功能可从 他们的表型。
