Frías vs Twin

Informations

This is a list of bus rapid transit (BRT) systems which are in operation or under construction. The term "BRT" has been applied to a wide range of bus services.

In 2012, the Institute for Transportation and Development Policy (ITDP) published a BRT Standard to make it easier to standardize and compare bus services.

Informations

Twins are two offspring produced by the same pregnancy. Twins can be either monozygotic ('identical'), meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic ('non-identical' or 'fraternal'), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell.

In contrast, a fetus that develops alone in the womb (the much more common case, in humans) is called a singleton, and the general term for one offspring of a multiple birth is a multiple. Unrelated look-alikes whose resemblance parallels that of twins are referred to as doppelgangers.
