You might suspect you are pregnant with multiples if you have more severe body changes, including: Identical twins are not dependent on race, country or ethnicity. Identical twins can also occur when one a woman has undergone fertility assistance and has had one fertilised egg returned to her uterus. If this egg then splits into two, an identical twin pregnancy can result. The most likely explanation for how they were formed is that two sperm cells – one with an x chromosome and one with a y chromosome – fused with a single egg.

They are the result of two sperm cells fertilising a single egg, which then divided to form two embryos – and each sperm contributed genes to each child. Multiple births can be fraternal, identical, or a combination. Small differences separate them and although at birth they can appear like little clones of each other, they are far from it.

But genetic tests show both are “chimeras”, and have some male cells – which have an x and y chromosome, and female cells – which have two x chromosomes. The twins are now toddlers, and doctors say they are progressing well. Essentially, the earlier the egg splits, the more independent each twin will be by having their own amnion, chorion and placenta.
