The Iberian Peninsula before the Bronze Age was genetically middle-neolithic-like, that is, like the Early Neolithic farmers but with an increased level of WHG. But no steppe ancestry present.
But here I don't want to estimate raw steppe ancestry, but the whole LN/BA package. I've estimated this input to be around ~50% in Spaniards.
Using the nMonte stats, spaniards can be modeled as being roughly 40-50% Central Euro BA, and 40-50% Neolithic farmer, and also, depending on the regions of Spain, some minor north-african and/or west-asian might be added to make it a better fit :
Spanish_Valencia
"Bell_Beaker_LN_Average" 39.75
"Stuttgart" 27.25
"Spain_MN__average" 15.7
"Unetice_BA" 14.95
"Mozabite_Berber" 2.35
Total of : 54.7% Central-Euro LN/BA + 43.0% Neolithic + 2.35% north-african
Other regions might get more Unetice than Bell Beaker :
Spanish_Aragon
"Spain_MN__average" 33.25
"Unetice__BA" 28.9
"Bell_Beaker_LN_Average" 19.45
"Stuttgart" 14.8
"Mozabite_Berber" 3.6
Total : 48.4% Central-Euro LN/BA + 48.1% Neolithic + 3.6 north-african
