What was the experimental purpose of the preliminary genetic screening performed in which Nüsslein-Volhard and Wieschaus exposed adult fruit flies to treatments that would cause mutations in their offspring?
A)to evaluate the mutagenic properties of varied treatments
B)to discover the bicoid gene
C)to generate two-tailed fruit-fly embryos
D)to identify fruit flies with mutations in genes that control fruit-fly development

Question

Quizplus · Accepted Answer

The purpose of the preliminary genetic screening was to identify fruit flies with mutations in genes that control fruit-fly development. By exposing adult fruit flies to mutagenic treatments, Nüsslein-Volhard and Wieschaus were able to generate offspring with random mutations. By analyzing the resulting embryos, they were able to identify fruit flies with mutations in genes involved in developmental processes.
