ز fertilization is the process where a sperm cell from a male merges with an egg cell from a female, leading to the formation of a zygote. This event typically occurs in the female reproductive system, specifically in the fallopian tubes. The zygote then begins to divide and develop into an embryo. This process is crucial for sexual reproduction in many organisms, including humans. Successful fertilization can result in pregnancy, where the embryo implants itself in the uterus and continues to grow, eventually leading to the birth of a new individual.
