Dizygotic Twins
1997: Idiopathic scoliosis in twins
What's a Dizygotic (fraternal) twin?
Dizygotic (fraternal) Twins
Does anyone on here believe that brothers and sisters are typically 62.5% concordant for Scoliosis? Put simply if a child has Scoliosis every one of his brothers and sisters has a roughly 2 out of 3 chance to also have Scoliosis.
That's not just bunk, that's UBER-bunk!
1997: Idiopathic scoliosis in twins
We investigated 21 pairs of twins for zygosity and idiopathic scoliosis. DNA fingerprinting confirmed that 13 pairs were monozygotic and eight were dizygotic. There was concordance for idiopathic scoliosis in 92.3% of monozygotic and 62.5% of dizygotic twins.
Dizygotic (fraternal) Twins
When two eggs are independently fertilized by two different sperm cells, DZ twins result.
DZ twins are simply brothers and/or sisters who happen to be the same age.
That's not just bunk, that's UBER-bunk!
