Two typical siblings will have about 50% of their alleles in common due to the law of independent assortment, which states that each allele segregates independently during gamete formation. This means that each sibling has a 50% chance of receiving a certain allele from each parent, resulting in about 50% of their alleles being the same. Monozygotic twins come from the same fertilized egg and share 100% of their alleles, while dizygotic twins come from two different fertilized eggs and share about 50% of their alleles like typical siblings.
