The relative minor: the same notes as the major scale three frets up, starting from the sixth degree.
1 2 b3 4 5 b6 7 · A B C D E F G#

Natural minor with a raised seventh, which gives minor keys their strong V chord and that classical, flamenco, and neoclassical metal flavor.
1 2 b3 4 5 6 7 · A B C D E F# G#

Natural minor with raised sixth and seventh, shown here in its jazz form (the same notes going up and down).
They share the first five notes. Natural minor has a flat sixth and flat seventh. Harmonic minor raises the seventh, which creates a strong dominant chord and a wide step between the sixth and seventh degrees. Melodic minor raises both the sixth and the seventh; on this chart it is shown in its jazz form, with the same notes going up and down.
Count down three frets from the major root, or take the sixth note of the major scale. C major and A minor share the same notes; G major and E minor do too. The charts here use that relationship, so the minor scales default to A while the major scale defaults to C.
Because that is the correct spelling for that key. A# harmonic minor, for example, raises its seventh from G# to G##. Each note keeps the letter its scale degree demands so the scale reads as seven different letters.
