Sexual reproduction is a biological process where two organisms combine their genetic material to create offspring. This usually involves a male and a female, each contributing a set of genes through specialized cells called sperm and eggs. The fusion of these cells results in a new organism that has traits from both parents, promoting genetic diversity. This method of reproduction is common in many species, including humans, animals, and plants. The mixing of genes helps populations adapt to changing environments and can lead to the evolution of new traits over generations. Overall, sexual reproduction plays a crucial role in the survival of species.
