Burt Jenner hopes Caitlyn Jenner will be a "better person".
The 36-year-old businessman hopes the 65-year-old former Olympian - who was previously known as Bruce Jenner before undergoing a gender transition - will be able to be a better parental figure.
He said: "At the end of the day there's no way I can get around it. I am ungodly thankful and I feel very fortunate to not have had my father in my life ... I learned how to open doors and shake hands and look people in the eye. Things that my dad never would have taught me ...
"I have high hopes that Caitlyn is a better person than Bruce. I'm very much looking forward to that."
Burt also admitted he blames E! reality show 'Keeping Up With The Kardashians' for being the "nail in the coffin" for their relationship.
He added: "I think the nail in the coffin for the relationship was the beginning of the TV show. There was a you-aren't-part-of-this kind of thing. Kris made the choice to make a good TV show that was in their image and brand."
Meanwhile, Caitlyn admitted she had "made a lot of mistakes" when it came to her eldest children: Burt, Brody, Brandon and Casey.
She told Vanity Fair magazine: "I have made a lot of mistakes raising the four Jenner kids. I had times not only dealing with my own issues but exes.
"[It was] very traumatic and there was a lot of turmoil in my life, and I wasn't as close to my kids as I should have been."
