The left and right handed fermion zero-modes are examined. Their behaviourunder the variation of the size of the instanton, $\ri$, and the size of theHiggs core, $\rh$, for a range of Yukawa couplings corresponding to the fermionmasses in the electroweak theory are studied. It is shown that thecharacteristic radii of the zero-modes, in particlar those the left handedfermions, are locked to the instanton size, and are not affected by thevariation of $\rh$, except for fermion masses much larger than those in thestandard electroweak theory.Comment: 8 Pages.
