There's no answer to that.

Miscegenation laws were once in place in many states, prohibiting interracial marriages.

Zero. Interracial marriage bans were officially struck down by the 1967 Supreme Court decision of Loving v. Virginia, although states still continued to have the laws on the books. In 2000, Alabama became the last state to repeal its interracial marriage ban.

Miscegenation is the usual term for this among humans. There used to be laws against it in the United States. There are probably still laws against it in other countries.
