A mutant is a living thing that has developed a difference from its parents because of a change in its genes. Genes are the instructions inside every cell that determine traits like eye color, height, or how a flower blooms. Sometimes these instructions change randomly, creating something new and unexpected.

In nature, mutations happen all the time. A mutant apple tree might grow fruit that's sweeter than usual, or a mutant butterfly might have slightly different wing patterns. Most mutations are tiny and barely noticeable, but occasionally one creates a significant change. The white tigers you see in zoos? They're mutants with a rare genetic change that gives them their striking coloring. Seedless oranges started as mutants too.

Scientists study mutants to understand how life works and evolves. In labs, researchers create mutant bacteria or fruit flies to learn how specific genes affect growth, behavior, or disease resistance. The discoveries from studying mutants have led to medical breakthroughs and better crops.

In comic books and movies, mutants often have dramatic superpowers, which makes for exciting stories but isn't how real mutations work. Real genetic changes are usually subtle: a slightly different enzyme, an unusual coloring, or resistance to a particular disease. While fictional mutants might shoot lasers from their eyes, real mutants are nature's experiments, testing out small variations that sometimes succeed and sometimes don't.
