Final answer:

The expression of Hucke beIN, tailless, and Bicoid in Drosophila embryos does not lead to any of the provided answer choices; instead, Hox genes, like these, are crucial for determining body segmentation and organ placement during development.

Step-by-step explanation:

When Hucke beIN, tailless, and Bicoid are expressed together in Drosophila embryos, it does not result in any of the options provided (formation of extra legs, suppression of eye development, or enhanced wing development). Instead, the expression of Hox genes, which includes the aforementioned genes, typically dictates the body segmentation and general body plan of an animal during development. A Hox gene mutation can lead to significant developmental changes such as the formation of legs where antennae should be or changes in body segmentation. As seen in the provided information, a mutant like Antennapedia in Drosophila can result in legs growing from the head, indicating the powerful role Hox genes play in determining appendage placement.
