A girl’s mother’s new husband’s son (the boy) from the husband’s prior marriage is what relation to the girl? The girl doesn’t share either genetic parent with the boy. The girl has half the genes of her mother, and the boy has half the genes of his father. But there’s no genetic overlap between the girl and the boy. Some would use the term non-genetic brother. Is there a more accurate or more accepted term? ~~ Nehmo ************** Step brother (or sister) is the usual term if there's no blood relationship. Lesley Robertson
