Do Telepathic Talent and an elan’s resistance stack?

Do racial traits bonus stack?

Telepathic Talent:

Benefit: You can expend your psionic focus to gain a +2 trait bonus to your saves against mind-affecting powers and psi-like abilities. This talent grants no benefit if you do not have the ability to gain psionic focus.

and

Elan

Resistance (Su): Elans can use psionic energy to increase their resistance to various forms of attack. As an immediate action, an elan can spend 1 power point to gain a +4 racial bonus on saving throws until the beginning of her next action.

if I’m a elan (with focus), if is a mind-affecting power to resist, Can I use both?
