You are researching the development of a novel type of winged insect isolated from the Amazonian rain forest. In order to find developmental mutants, you expose a population to X-ray radiation and examine the resulting larvae microscopically. You identify a non-viable single gene mutant that is missing wings but carries legs on the segment where the wings should be.

Compare your result with what is known about the types of genes important in pattern formation in the model organism Drosophila melanogaster.

Within what type of gene important in normal pattern formation do you predict the mutation you have just discovered is located?


Within a maternal effect gene.


Within a gap gene.


Within a homeotic gene.


Within a pair-rule gene.


Within a segment polarity gene.
