In spite of this, Betty is portrayed as having a distinctly emotional marriage with Barney, which often includes pet names and more obvious affection than the dynamic and energetic interaction between Fred and Wilma.

Occasions when Betty leads the action are extremely scarce: one episode centers around her working undercover as a gentle old lady to earn money for a present for Barney; in another, the plot focuses on her and Wilma's suspicions of Barney being involved with another woman (who turns out to be Fred in a disguise in order to attend a ball game free of charge).

This lack of protagonism (her continuous presence almost becoming a backdrop for supporting characters Pebbles, Bamm-Bamm and Dino) makes Betty less of the lead than the show's general concept might imply.

[7] Betty became a homemaker, keeping house with such prehistoric aids as a baby mammoth vacuum cleaner, pelican washing machine, and so forth.

Betty, much like Wilma, also enjoyed volunteering for various charitable/women's organizations in Bedrock, shopping, and (occasionally) meeting the celebrities of their world, including "Stony Curtis", "Cary Granite", and "Ann-Margrock".

When Bamm-Bamm was a teenager, Betty gained employment as a reporter for one of Bedrock's newspapers, the Daily Granite (presumably a parody of the Daily Planet of Superman fame), under the editorial guidance of Lou Granite (presumably a parody of Lou Grant of the contemporaneous eponymous series, and formerly of The Mary Tyler Moore Show).

Jane Krakowski replaced O'Donnell in the 2000 prequel The Flintstones in Viva Rock Vegas, in which Betty's maiden name is "O'Shale".
