twinning

1. the production of symmetrical structures or parts by division.

2. the simultaneous intrauterine production of two or more embryos. Twinning is a desirable feature in animals that depend for their profitability on the production of young, e.g. lambs of the meat-producing breeds, and selection for the characteristic is a standard husbandry strategy. In animals that are essentially uniparous, e.g. mares, twins represent a danger to the foals and to the mare. Twins in which one is a female and one a male have the added risk of the female being a freemartin.

Q. How do I know whether I will get twins or not? Twins have always fascinated me and I cannot wait to get pregnant and have twins. My husband has already bought identical dresses hoping that we will be expecting twins shortly. As I am conceived now that I am pregnant, I am going for a test tomorrow. How do I know whether I will get twins or not?

A. do you have identical twins in your family? if so the chances of you having twins is greater, anyway, checking it out can be done only by ultrasound screening. only then they can see if there are two heartbeats and see two fetuses.
