if a pair of twins were to have a baby with another set of twins, would the babies come out identical?
In: Biology
A pair of identical twins having children with a pair of identical twins would result in children that look like siblings genetically, despite being cousins.
A pair of identical twins having children with a pair of fraternal twins would result in children that look like they fall somewhere between siblings and cousins. Specifically, they’d look like half siblings staying within the same family. Ie parent A has a child with parent B, and then also has one with parent B’s brother or sister.
A pair of fraternal twins having children with a pair of fraternal twins would result in children that look like cousins genetically, as expected.
Fraternal twins are two children born at the same time, made from 2 eggs, 2 sperm, and had 2 placentas. Identical twins are made from 1 egg and 1 sperm with 1 placenta, it just split into 2 embryos very early on. Fraternal twins just look like normal siblings genetically, but identical twins share the same exact DNA.
