In what way might gene duplication play a role in evolution?

Solution

Gene Duplication event may result in two or more copies of a single gene during evolution of the species. Gene duplications may result from errors during genetic material duplication events or during meosis events. If a gene has been duplicated in an organism, during the course of evolutionary time they may accumulate several mutations (point as well as insertions/deletions), which may lead to the change in their protein sequences with different functionalities or phenotypic characteristics. Since evolution is the not possible without the environmental selection events, the newly acquired characteristics from the duplicated gene must have to be selected for its newly developed function to meet with the requirement in line to adopt with new environmental challenges. Thus, it this way, the duplicated gene funtions as a raw material wherein the environment act upon it to shape and get develop in accordance with it to face the new challanges.
