Answer:
It is because of more hormone production
Explanation:
Some women are more likely than others to give birth to twins. The factors that increase the odds include: Advancing age of the mother – women in their 30s and 40s have higher levels of the sex hormone oestrogen than younger women, which means that their ovaries are stimulated to produce more than one egg at a time
It also occurs when the breakdown of the zygot occurs when meiosis occurs after fertilization
