Actually, not that much. Recent genetical studies have shown that almost nobody got left behind after the fall of Granada. We that were born in the South were said to be half Moors. But historical records, and now genetics, said that muslim inhabitants of Al Andalus fled in mass in 1492 to North Africa. South Andalusia was mostly repopulated with people from nothern kingdoms. Of course there's much cultural osmosis and there was muslim population left behind, just not in Andalusia.
