Mulattoes were the direct offspring of plantation rapes. Slave masters often threat the female slaves if they resist the masterâs desire of having intercourse. If they fought back, the female slaves will be whipped, will be beaten up, or worse of all, will be killed.
The term Mulatto typically meant a person of a white and black parentage or of two Mulatto parents. And like Whites and Blacks, Mulattos tend to vary in appea â¦ rance, facial features, and color tone of skin from darker to lighter.
