Gene duplication is a type of mutation where one gene is copied to a second location within the genome. The original location still contains the same gene, but now there are two locations with the gene. Evidence shows that this event has happened many times throughout the evolution of life. Why might gene duplication be advantageous to an organism undergoing adaptation?

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
