)) This passage describes the wing type trait in fruit flies: n )) Some scientists breed fruit flies to learn how traits are inherited. These scientists often use flies with vestigial wings, which are shorter and stubbier than normal wings. Fruit flies with vestigial wings cannot fly, so they are easier for scientists to handle and study. )) In a group of fruit flies, some individuals have normal wings and others have vestigial wings. In this group, the gene for the wing type trait has two alleles. The allele NW is for normal wings, and the allele n is for vestigial wings. )) A certain fruit fly is from this group. This fruit fly's phenotype for the wing type trait is normal wings. This fly's genotype for the wing type gene is NN. )) Based on this information, complete the following statement. )) This fruit fly is for the wing type gene. \")) heterozygous homozygous
