Secondo i risultati di questo studio sembra che l'immissione di elementi germanici in Spagna e Italia sia stato minimo. Questo in particolare nel caso italiano, dove i soliti propugnatori del mito nordicista facevano risalire proprio a questo presunto e 'invigorente' apporto di sangue nordico la causa scatenante del Rinascimento e della prosperità economica del settentrione italiano a esso coevo.
Un'altra bufala nordicista che come quella dell'impero romano decaduto perché 'negrizzato', finisce allegramente nella pattumiera.

Extent of Germanic Admixture in Iberia and Italy
The recent study on Y chromosome haplogroup I gives us the means to attempt a first-order quantification of the extent of Germanic admixture in parts of western Europe that were affected by the barbarian movements during and after the time of the western Roman empire's collapse.
Haplogroup I reaches high frequencies in the Germanic world, while its frequency in Italy and Iberia is low, making it an excellent candidate for this type of analysis. It is divided in three main clades:
* I1a originated in Franco-Cantabria and spread to northwestern Europe after the Last Glacial Maximum. Its maximum frequency today is in Norwegians (38.9%) and is frequent in Scandinavia and Germany (25%)
* I1b is divided into I1b2, frequent in Sardinia and Basque country, and undifferentiated I1b*, with a wide distribution and higher frequency, and a primary focus in the eastern Balkans (up to 40% in Bosnians). I1b* originated somewhere between the Adriatic and the Black Sea.
* I1c is correlated with I1a and shares a common haplotype with it, indicating a shared history of the two. Maximum frequency of 12.5% in Germans.
It should be stressed here that I originated in southern Europe and spread northwards after the LGM. But, given that today two particular clades (I1a+I1c) are very frequent among Germans compared to southern Europeans, we can hypothesize that any movement of Germanic speakers would introduce such chromosomes to the affected population.
I1a is found in Portuguese (1.3%), Catalans (3.1%), northern Italians (2.6%), central Italians (2%), Calabrians (0.7%), Italians of Albanian origin (1.3%), Italians from Apulia (1.3%). These numbers are less than 1/10 of the corresponding frequency in Germanic speakers.
I1c is found in Portuguese (1.6%), northern Italians (1%), central Italians (3%), Calabrians (1.4%), Italians of Albanian origin (3.8%), which are similarly less than 1/10 of the corresponding frequency.
In general, it appears that the introgression of Germanic elements into the Iberian and Italian peninsulas has been minimal. In particular, for the case of Italy where an "invigorating" Germanic admixture has been proposed by Teutonists as a cause of the Rennaissance and the economic prosperity of northern Italy, we observe that no such influence is observed.
While movements of peoples did in fact occur, causing the collapse of the western Empire, it appears that on the whole these did not alter the pre-existing genetic composition of the indigenous populations.
