    I have just noticed that all the major as well as all the minor arpeggios that occour naturally in the major scale are similar to one another except for the mixolodian mode. How come?

    Short answer because the chord built on the 5th of the scale is Dominant the chord built on the seventh degree of the scale is half diminished.

    Long answer:

    It has to do with the whole step half step pattern and that the arpeggios for chords built from each note of the scale are done in 3rds.
