Explanation:
Detailed explanation-1: -Would it be possible to study this same gene in fruit flies? Explain. Yes-if the same gene is found in nematodes and humans, it was found in the common ancestor of protostomes and deuterostomes. If so then fruit flies should also have this gene.
Detailed explanation-2: -For instance, a wild-type fly (with red eyes and a yellow body) has one of four possible genotypes: EEBB, EEBb, EeBB, and EeBb. There is no way to tell these genotypes apart visually, but there is a well-established experimental technique to determine the fly’s genetic makeup.
