Had there not been segregation and Jim Crow, would modern Americans look like modern Brazilians?

Antimiscigenation laws existed in the US until the 1960s.

Depends on the state, not federal law.

Not much of a difference. Prior to WWll the USA was more tribal. As an example where my Mom's side of the family grew up there was
2 catholic churches, St. Boniface (for Germans) and St. Patricks (for Irish). There wasn't really that much intermarrying among whites relative to country or origin, religion, let alone race/eithnic stuff. There was some of course. I think you started seeing some changes in the 60's with the invention and popularity of the Suburb and the interstate highway system. Prior to that people kinda lived in country of origin hoods only.
It would have semi scandalous for a Catholic to marry some type of protestant back then.

Brazil's early immigration ad formation was a lot different than the USA

True, but at their 'peak', anti-miscegenation laws were present in 33 states.

"According to some Historians, Portuguese settlers in Brazil used to prefer to marry Portuguese-born females. If not possible, the second option were Brazilian-born females of recent Portuguese background. The third option were Brazilian-born women of distant Portuguese ancestry. However, the number of White females in Brazil was very low during the Colonial period, causing a large number of interracial relationships in the country.

White/Black relationships in Brazil started as early as the first Africans were brought as slaves in 1550 where many portuguese men starting marrying black women. The Mulattoes (people of White/Black ancestry) were also enslaved, though some children of rich aristocrats and owners of gold mines were educated and became important people in Colonial Brazil. Probably, the most famous case was Chica da Silva, a mixed-race Brazilian slave who married a rich gold mine owner and became one of the richest people in Brazil

Other mulattoes largely contributed to Brazil's culture: Aleijadinho (sculptor and architect), Machado de Assis (writer), Lima Barreto (writer), Chiquinha Gonzaga (composer), etc.

In 1835, Blacks would have made up the majority of Brazil's population, according to a more recent estimate quoted by Thomas Skidmore. In 1872, their number was shown to be much smaller according to the census of that time, outnumbered by pardos and Whites."

"Depends on the State" it was a law in the whole SOUTH, where, let me tell you: Most black people lives and have roots.

[Petalpusher]

It is like Brazil, but just for African Americans being up to 1/4 white.

[skain]

The Southern Cone hardly has any Blacks for a start (except some poorer areas of Montevideo).

Still with a Lot mestizos.

I know what you mean, but had those laws not existed wouldn't have mixed-race relationships become much more common still, to the point that the US would be barely if at all whiter than Brazil?

True, but I'm thinking primarily of White-Black mixes here.
