• Synonym家系かけいWrittenWritten. A family line passed down the generations, as in 「医者の家系」; stresses the family's continuity, while 「血統」 stresses inherited blood and covers animals too.
• Synonym血筋ちすじNeutralNeutral. Native word for blood ties and family standing that can also mean blood vessels; stresses kinship, and in the lineage sense is close to 「血統」.
• Synonym家筋いえすじWrittenWritten. The bloodline a family has handed down for generations; the emphasis is on the family line as such, while 「血統」 centers on the blood inherited from ancestors.

• Related素性すじょうNeutralNeutral. A person's origins, identity and background, often in 「素性の知れない」; it is more about who someone is, where 「血統」 covers only blood.
• Related家柄いえがらNeutralNeutral. Family standing and pedigree, as in 「家柄がいい」; it is about social rank, while 「血統」 speaks only of blood.
• Related毛並みけなみCasualColloquial. Literally the condition and lie of an animal's coat, also breed; 「毛並みがいい」 figuratively praises someone's background, while 「血統」 states blood directly.
• Related生まれうまれCasualColloquial. Birth or birthplace, as in 「東京生まれ」; it points to when and where a person was born, while 「血統」 traces back through ancestors.
• Related身元みもとNeutralNeutral. Someone's identity and background, as in 「身元確認」; it is about establishing who a person is, unlike 「血統」, which only traces blood.

• Related氏素性うじすじょうWrittenWritten. A person's family background, in set phrases like 「氏素性も知れない」; it reaches into identity and background more than 「血統」, which is blood alone.

「血統」 is the default for blood inherited from ancestors, said of people and animals alike, as in 「血統書付きの犬」 and 「名門の血統」. Say 「家系」 for a family line down the generations, 「家柄」 for a family's standing, 「出自」 or 「素性」 for origins. 「系譜」「系図」 are records; 「身元」「氏素性」 concern identity; 「系統」「系」 are broader, matching 「血統」 only in the bloodline sense; 「毛並み」 is figurative; 「生まれ」 is about birth.
