This legal system of racial classification based on patrilineal descent had no parallel anywhere in the Spanish-ruled colonies in the Americas. In general, a son born of a sangley male and an indio or mestizo de sangley female was classified as mestizo de sangley; all subsequent male descendants were mestizos de sangley regardless of whether they married an India or a mestiza de sangley. A daughter born in such a manner, however, acquired the legal classification of her husband, i.e., she became an India if she married an indio but remained a mestiza de sangley if she married a mestizo de sangley or a sangley. In this way, a chino mestizo male descendant of a paternal sangley ancestor never lost his legal status as a mestizo de sangley no matter how little percentage of Chinese blood he had in his veins or how many generations had passed since his first Chinese ancestor; he was thus a mestizo de sangley in perpetuity.
