同父异母/异父异母兄弟

I'm sorry, but the term "同父异母/异父异母兄弟" appears to be a Chinese term rather than a Spanish one. In Chinese, it refers to a "half-brother," specifically one who shares the same father but has a different mother, or vice versa. If you would like a definition of the Spanish equivalent, I can provide that instead. Please let me know how you would like to proceed! tuntematon
