Final answer:
Increased wnt gene expression can affect the expression of Bar-1.
Step-by-step explanation:
The question is asking about the effect of increased wnt gene expression on the expression of Bar-1. The wnt transcription pathway plays a key role in animal development and can cause changes in gene expression. Increased wnt gene expression would lead to increased activation of the wnt pathway, which in turn can affect the expression of Bar-1.
