The preliminary genetic screening performed by Nüsslein-Volhard and Wieschaus was focused on identifying fruit flies with mutations in genes that control fruit-fly development. They wanted to study the genetic basis of early embryonic development in fruit flies, so they screened thousands of flies and identified mutants with abnormal embryonic development. This allowed them to identify genes that are required for normal development and study the functions of these genes in more detail.
