Question: Why do individuals from the same family have different personalities? Analysis: When answering this question, you can consider from two aspects: genetics and environment. First, although family members share the same genes, genetic variations and gene recombination can lead to each person having a unique genetic combination, which may affect their personality traits. Second, even if family members live in the same household environment, they will also be influenced by different external environments, such as school, friends, and social environment, all of which can affect individual personality development. Additionally, one's experiences, education, and personal choices will also shape their personality. When providing an answer, incorporating specific examples or personal experiences will be more convincing.

問題：為什麼來自同一個家庭的個體會有不同的性格？ 解析： 在回答這個問題時，你可以從遺傳和環境兩個方面來考慮。首先，雖然家庭成員共享相同的基因，但遺傳變異和基因重組會導致每個人都有獨特的基因組合，這可能影響他們的性格特徵。 其次，即使家庭成員生活在相同的家庭環境中，他們也會受到不同的外部環境影響，例如學校、朋友和社會環境，這些都會影響個體的性格發展。同時，個人的經歷、教育和個人選擇也會塑造他們的性格。在給出答案時，結合一些具體的例子或個人經歷會更有說服力。
