During asymmetric cell division, cells divide such that the mitotic spindles are oriented perpendicular to the plane on which the cells reside. What types of cells are the original parent cells and how does this affect cell lineage?

Homeobox (Hox) genes are essential regulators of development of an organism, as they define region specific development of an embryo along its anterior-posterioir axis. A mutation in the gene Antennapedia, for example, causes Drosophila melanogaster to grow legs from its head instead of antennae.

Given that hox genes regulate segmental identity of an organism, which of the following phenotypes would possibly be present in a fruit fly with a mutation in a Hox gene required for formation of very anterior structures?
