A segment saying that chromosomes determine one's gender on an episode of the educational children's show "Bill Nye the Science guy," is cut out on the Netflix version.

Netflix did not edit Bill Nye The Science Guy. The series was delivered that way by Buena Vista TV, according to a Netflix spokesperson.

In the original episode, titled "Probability," a young woman told viewers, "I'm a girl. Could have just as easily been a boy, though, because the probability of becoming a girl is always 1 in 2."

"See, inside each of our cells are these things called chromosomes, and they control whether we become a boy or a girl, " the young woman continued. "See, there are only two possibilities: XX, a girl, or XY, a boy."

But in the version of the episode uploaded to Netflix, the segment has been cut entirely. While noncontroversial at the time, the 1996 segment appears to contradict Netflix's new series "Bill Nye Saves the World."

The new show endorses a socially liberal understanding of gender, under which gender is defined by self-identification rather than genetics and there are more than just the two traditional genders.

Update May 5, 2017 9:28 a.m.: This post has been updated to reflect comment from Netflix, which says it did not have a role in cutting the segment from the episode.
