The legendary Amazon women did exist

… but what were the blood type distributions among them?

Let’s see:

Some Scythian-Sarmatian cultures may have given rise to Greek stories of Amazons. Graves of armed females have been found in southern Ukraine and Russia. David Anthony notes, “About 20% of Scythian-Sarmatian ‘warrior graves’ on the lower Don and lower Volga contained females dressed for battle as if they were men, a style that may have inspired the Greek tales about the Amazons.

The Sarmatians differed from the Scythians in their veneration of the god of fire rather than god of nature, and women’s prominent role in warfare, which possibly served as the inspiration for the Amazons.

Who were the Sarmatians?

The Sarmatians (Latin: Sarmatae, Sauromatae) were a large
Iranian confederation that existed in classical antiquity, flourishing from about the 5th century BC to the 4th century AD.

Originating in the central parts of the Eurasian Steppe, the Sarmatians were part of the wider Scythian cultures.

Oleg Trubachyov derived the name from the Indo-Aryan *sar-ma(n)t (feminine – rich in women, ruled by women), the Indo-Aryan and Indo-Iranian word *sar- (woman) and the Indo-Iranian adjective suffix -ma(n)t/wa(n)t.

By this derivation was noted the unusual high status of women (matriarchy) from the Greek point of view and went to the invention of
Amazons (thus the Greek name for Sarmatians as Sarmatai Gynaikokratoumenoi, ruled by women).

Herodotus (Histories 4.21) in the 5th century BC placed the land of the Sarmatians east of the Tanais, beginning at the corner of the Maeotian Lake, stretching northwards for fifteen days’ journey, adjacent to the forested land of the Budinoi.

Herodotus (4.110–117) recounts that the Sauromatians arose from marriages of a group of Amazons and young Scythian men. In the story, some Amazons were captured in battle by Greeks in Pontus (northern Turkey) near the river Thermodon, and the captives were loaded into three boats. They overcame their captors while at sea, but were not able sailors. Their ships were blown north to the Maeotian Lake (the Sea of Azov) onto the shore of Scythia near the cliff region (today’s southeastern Crimea). After encountering the Scythians and learning the Scythian language, they agreed to marry Scythian men, but only on the condition that they move away and not be required to follow the customs of Scythian women. According to Herodotus, the descendants of this band settled toward the northeast beyond the Tanais (Don) river and became the Sauromatians.
Herodotus’ account explains the origins of their language as an “impure” form of Scythian. He credits the unusual social freedoms of Sauromatae women, including participation in warfare, as an inheritance from their Amazon ancestors. Later writers refer to the “woman-ruled Sarmatae“.

Again:

Archaeological evidence suggests that Scythian-Sarmatian cultures may have given rise to the Greek legends of Amazons. Graves of armed females have been found in southern Ukraine and Russia. David Anthony notes,
“About 20% of Scythian-Sarmatian “warrior graves” on the lower Don and lower Volga contained females dressed for battle as if they were men, a phenomenon that probably inspired the Greek tales about the Amazons.
