These twins have four arms; one, two, three or four legs; and typically one set of external genitalia and one anus. [13] Survival rate is 63%.

These twins have four arms, and two, three, or four legs. [13]
In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Fertilization occurs when the sperm cell successfully enters and fuses with an egg cell (ovum). The genetic material of the sperm and egg then combine to form the single cell zygote and the germinal stage of development commences.

A tragic photo of a baby born with only one eye and no nose has been circulating the Internet. The baby is being referred to as "baby cyclops" due to the comparisons drawn with the mythical cyclops.
The zygote is the earliest developmental stage. In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. The formation of a totipotent zygote with the potential to produce a whole organism depends on epigenetic reprogramming.
