European Maternal ancestry in South Brazil

[Zumbi]

Higher than i expected to be honest

Close to 64% of the pop have european maternal haplogroups

The 63.8% of mtDNA lineages of European ancestry found in our study is notably higher than the overall frequency reported by Alves-Silva et al.[3] for the Brazilian population (39.0%) and, at the sametime, is very similar to the frequency estimated in thesame study for the southern part of the country (66.0%).

The African haplogroups L0, L1, L2, and L3 were alsorelatively common in Santa Catarina (15.0%). African haplogroups arrived in the New World with the slave tradefrom the sixteenth century onwards [36,37]. The frequencyof African haplogroups in Brazilians from Santa Catarinawas lower than in the Brazilian population as a whole(28.0%), but similar to that estimated for the wholesouthern part of the country (12.0%) [3].

The four Native American haplogroups (A, B, C, and D)appeared well represented in Santa Catarina with a totalfrequency of 21.3% (Table 2), practically identical to thatestimated by Alves-Silva et al. [3] for Southern Brazil(22.0%).

So basically, Indian and African mtDNA is located in place where Slaves landed off and worked for the second, and early area of portuguese exploration for the first ?

More of less something like that
The south was settled in a different way,many couples arrived in the 18th century.
That's certainly one the reasons for the higher european maternal input,it is not only because of the 19th-20th century immigration.


"The impact of Azorean immigration to southern Brazil was so strong that in 1780 the Azoreans accounted for 55% of the entire population of the captaincy of Rio Grande do Sul.[35] The fertility of Azorean couples was enormous. Rare was the couple that did not have more than six children. Some, like one Lopes, reached the fabulous number of twenty-one children; that of a Manuel Jacintho, that of thirty children, fifteen from each of the women he was married to.[36]

A study from the northeast region who is the oldest region of the country and one of the main destinations of slaves show a very different pattern
"Overall, results showed that the population of the Northeastern region of Brazil has Amerindian mitochondrial ancestry as the most frequent, representing 43.5% of the individuals, followed by African (37.8%), European (16.6%), and non-Amerindian Asian (2.1%) (Table 2)."

Yeah that's a lot, what's the region with the most euro in mtDNA in latam?
If i remember correctly, the mt in Paraguay is about 90 amerindian.

My maternal halogroup is K and I'm southern brazilian from Santa Catarina. I'm sure african and ameridian maternal lineages are more common in Rio Grande do Sul and Paraná.

And your Y-DNA bro?

[Catarinense1998]

And your Y-DNA bro?

What's up? My paternal one is E, but I don't know what variant it is. I asked Token (brazilian member, he knows a lot about this topic) and he told me that there's some variants of the E lineages, some E lineages arrived in Iberia during the roman times via North Africa (E-M81), and the other branch (E-V13) came from the Balkans since lot of roman soldiers from Balkans settled in Iberia.

The same is true about my maternal halogroup. It's K, but there's two K clusters: one belongs to the indo-european branch and the other branch is anatolian and I don't know for sure what's mine.

I find kinda funny that the native haplos are a b c d.I wonder if that was an accident.

Oh yeah, trying to figure out a mtdna if is MENA or European is hard due they don't mutate often like the Y-DNA does (In addition to the genetic flow that men have left over time since they were the most daring to go to other lands and stuff like that).

Can I know what DNA test did you do to know your Y-DNA?

[Zumbi]

This study from Santa Catarina is the study that shows that highest % of european mtDNA that i have ever seen from LATAM.
There is another study from Argentina that also shows a large euro mtDNA contribution,like 50% if i recall exactly.

The countryside of southern brazil is probably the area with the largest influence of euro mtDNA if i had to guess,there are cities that were literally founded by germans and italians(many of them brought woman with them)
