So...Magic. Magic is totally the reason.

(For those curious; Karliah's mom was Dralsi Indoril, Dralsi is Queen Barenziah's daugther, Barenziah boinked a Drayven Indoril disguised via magicka as Jagar Tharn, which resulted in Dralsi.)

Thats total bullsh+t, dude. Jagar Tharn never was Breton, but an Imperial in fact. In the Books "The true Barenziah" is also said, that a Bosmeri woman gave birth to him in Valenwood, whist being a mixblood of Altmer and Dunmer, like the novel series also suggest and hoaxed the Imperials with pretending and living as the Emperor for a year before he got killed for unknown reasons.

He never became or shapeshifted himself as Drayven Indoril. They worked together and it was Drayven himself who seduced Barenziah. Get your facts right, fetcher.
