In Drosophila, absence of Bicoid protein results in larvae missing anterior segments and absence of Nanos protein results in larvae missing posterior segments. Suppose you inject Nanos protein into the anterior region of early embryos lacking Bicoid. The expected result would be:
A)larvae like bicoid mutants.
B)larvae like nanos mutants.
C)larvae with two anterior regions.
D)larvae with two posterior regions.
E)None of the answer options is correct.

Injecting Nanos protein into the anterior region of early embryos lacking Bicoid would result in the activation of posterior genes in the anterior region, leading to the development of two posterior regions and no anterior regions. Therefore, the larvae would have two posterior regions, similar to nanos mutants.
