Predict what would happen if a fruit fly regulatory gene that codes for a leg replaced a frog gene in the same position.

Question

Quizplus · Accepted Answer

Different organisms have different developmental pathways and regulatory mechanisms that govern their gene expression. If a fruit fly regulatory gene replaced a frog gene in the same position, it is likely that the gene would only function properly in a fruit fly context and be unable to regulate the expression of genes required for a frog leg. Therefore, the frog would still produce a frog leg as the regulatory gene may not have significant effect on the final leg structure.
