Siblings can be the same age, in the form of twins and triplets, and other various forms of the multiple births.
siblings
Two twins are two people. Twins are siblings born at the same time, sharing the same age and often a strong physical resemblance.
yes they are twins and siblings too at that.
The Duggar children closest in age are the twins, as they were only born minutes apart. Other than the twins, the closest births are Jordyn and Josie, at 8 days less than a year. Jordyn was born on December 18, 2008, and Josie was born on December 10, 2008. However, Josie was born four months premature, so if she was born on or around her due date, they would not be the closest in age.
Identical twins have the closest DNA match, as they share virtually all of their DNA. Siblings, on the other hand, share about 50% of their DNA. Parents and children also have a close DNA match, with children inheriting 50% of their DNA from each parent.
Some of the Duggar children were born just minutes apart because there are two sets of twins in the family.
No, you shouldn't need to raise them any differently. Fraternal twins are no more alike than two siblings...i know from experience that most twins like to be treated as, well...not twins. When you think about it, all they really are is siblings that are born at the same time. If you had a son who was 8, and a daughter who was 12; fraternal twins would be no different to these two siblings if they were both 8 or both 12.
Fraternal twins are two siblings that have the same birth day, but do not look identical.

No, the correct term is "twins." "Two twins" is redundant because twins refers to a pair of siblings born from the same pregnancy.
The sisters could be the result of two separate sets of identical twins who married each other and had children. This would mean that genetically, the sisters are siblings, but due to the unique combination of DNA from both sets of twins, they appear very similar in appearance and age.
Alec and Jane,they are bio twins
