Sex determination is the process by which an organism develops as male or female. In humans, this is mainly controlled by the pair of sex chromosomes inherited. If an individual inherits two X chromosomes, they will develop as female; if they inherit one X and one Y chromosome, they will develop as male. However, sex determination can also be influenced by other factors, such as hormones during development. While most animals use chromosomes to determine sex, some organisms, like certain reptiles, rely on environmental factors such as temperature. Understanding sex determination helps us learn how traits are passed from parents to offspring.
