Identify the reasons for the sex-ratio to be in favour of females. |
|
Answer» Historically, all over the world it has been found that there are slightly more females than males in most countries. This seems to be due to two reasons. First, girl babies appear to have an advantage over boy babies in terms of resistance to disease in infancy. At the other end of the life cycle, women have tended to outlive men in most societies, so that there are older women than men. |
