Question

You discover a gene for the production of fur in mammals. You examine the gene regulation in the genomes of monkey, bear, zebrafish, wolf, and snake, and all of the genomes have an orthologous gene. What does analysis of the orthologous gene tell you about the function of the gene controlling the trait

Answer 1

The analysis or evaluation of the orthologous gene tells one regarding the function of the gene monitoring the trait, that is, the ancestral form of the gene was probably taking part in a different biological function and do not need to get restricted to the production of fur. Thus, the function of the gene is not restricted to production of fur, and the gene may function in another procedure, which is witnessed in all of the species.
