What is a Sororal twin?
Dizygotic (DZ) or fraternal twins (also referred to as "non-identical twins", "dissimilar twins", "biovular twins", and, informally in the case of females, "sororal twins") usually occur when two fertilized eggs are implanted in the uterus wall at the same time.
Fraternal twins, on the other hand, are as alike as any two siblings. They may look very different. Or, they may indeed be so similar that they are assumed to be identical, just as some siblings would be remarkably indistinguishable, if only they were the same age.
- To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To form fraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and produce two genetically unique children.
- But if you look closely, they are still not exactly the same. They will always have some physical differences due to differences in their environment. Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA.
- Fraternal twins are really just siblings who share the same womb. Each starts out as a separate egg fertilized by a separate sperm. They don't share any more DNA than do any two siblings. Siblings normally have 50% of their DNA the same.
They had assumed their whole lives they were, but they never got a Twin Zygosity DNA Test to prove it. On the surface, it might seem clear Tia and Tamera are identical, and there might be a question of why a DNA test was even needed. Sometimes twins look alike, but they are technically only fraternal twins.
- Tia is two minutes younger than her twin sister, Tamera. Tamera was born first, at 4:30pm, followed by Tia at 4:32pm. She also has two younger brothers, actor Tahj Mowry and Tavior Mowry, who played college football for University of California, Davis.
- Tamera Mowry net worth: Tamera Mowry is an American actress who has a net worth of $4 million dollars. Born in Gelnhausen, Germany, Tamera Mowry moved to the United States with her family when she was a child. She, and her twin sister, Tia, began acting in the early 90s, and were managed by their mother.
- Rachel True net worth: Rachel True is an American actress and model who has a net worth of $500 thousand. Rachel True was born in New York City, New York in November 1966. One of her best known roles came starring as Mona Thorne in the television series Half & Half from 2002 to 2006.
