Zygotic lethals with specific maternal effect phenotypes in Drosophila melanogaster. I. Loci on the X chromosome.
In order to identify all X-linked zygotic lethal loci that exhibit a specific maternal effect on embryonic development, germline clonal analyses of X-linked zygotic lethal mutations have been performed. Two strategies were employed. In Screen A germline clonal analysis of 441 mutations at 211 previously mapped X-linked loci within defined regions was performed. In Screen B germline clonal analysis of 581 larval and pupal mutations distributed throughout the entire length of the X chromosome was performed. These approaches provide an 86% level of saturation for X-linked late zygotic lethals (larval and pupal) with specific maternal effect embryonic lethal phenotypes. The maternal effect phenotypes of these mutations are described.
