Why is it that the Lord-Protector of Lanachrona has no Talent, even though he is a descendant of a Talent wielder?

Actually, both Mykel, the very first Protector of Tempre, and his wife Rachyla have Talent, but the problem is that subsequent generations of Lords-Protector did not always marry those with Talent, and the gene for Talent tended to get bred out of the line. This issue comes up in The Lord-Protector’s Daughter, coming out from Tor in hardcover in November.
