Quizplus · Accepted Answer

Fraternal twins are siblings conceived at the same time but with different eggs and sperm, making them genetically similar to regular siblings with an average of 50% genetic similarity, which falls within the 40% to 60% range. Identical twins share nearly 100% of their genes, cousins share about 12.5%, and adopted siblings share no genetic material by definition, as their relationship is legal, not biological.
