title: A temperature-sensitive mutant affecting the process of chorion gene amplification in Drosophila melanogaster.
abstract: K575 is a temperature-sensitive female sterile mutant which shows abnormal chorion structure and subnormal amounts of the major chorion proteins at the restrictive temperature. These phenotypes apparently result from a temperature-sensitive defect in amplification. Both clusters of chorion genes are affected, indicating that the gene operates in trans.
