On that basis we can say that while chance of finding one double-yolk egg may be 1/1000, the chance of finding a second is considerably higher – more like 1/100.
At what point does an egg split into twins?
Zygotic splitting occurs between days two and six when the zygote divides, usually into two, and each zygote then goes on to develop into an embryo, leading to identical twins (or triplets if it divides into three). These are known as “monozygotic” twins (or triplets).
