Across the Strait of Gibraltar, a 22-point gap in one deep-ancestry component.

The Moroccan Arab reference is modeled as 26.7% Iberomaurusian, 25.2% Anatolian Neolithic Farmer and 24.2% Levantine Neolithic Farmer. Its full breakdown also includes 11.6% West African, 9.5% Western Steppe Herder, 2.1% Zagros Neolithic Farmer and 0.7% Nilotic.

The Andalusian reference has 55.0% Anatolian Neolithic Farmer, 28.8% Western Steppe Herder, 11.5% Western Hunter-Gatherer and 4.7% Iberomaurusian. Farmer- and steppe-related components are higher here; the Moroccan reference has a larger Iberomaurusian component, associated with prehistoric North Africa.

Modern matches place the Moroccan reference closest to Moroccan Arabs from Casablanca (1.490). Algerian Arabs from Algiers (1.588) and Algerian Mozabites (1.929) are also very close. The national-flag cards select Algiers and Mauritanian Arab Beidan (2.692), avoiding repeated country flags.

For Andalusians, Portuguese are the nearest match (0.801), followed by Castilla-La Mancha (0.843), Murcia (0.852), Galicia (1.009) and Extremadura (1.020). Hispano-Cubans (1.060) supply the next distinct country flag on the slide; that reference is not the whole Cuban population.

The exact Moroccan Arab–Andalusian distance is 21.263, labeled distant. Moroccan regional references vary: the Morisco Tétouan average is closer to Andalusians at 7.708. One broad reference does not capture every regional or family history.

These are model-based population averages, not fixed ethnic recipes. Small components do not prove a recent ancestor from the named region, and genetic distance is not a percentage of shared DNA.
