Explanation:

All pregnancies start when a sperm fertilises an egg. This fertilised egg is called a zygote. Sometimes a woman's ovaries release two eggs, and two separate sperm fertilise each egg. ... These twins are called fraternal twins, dizygotic twins (meaning two zygotes) or non-identical twins.
