After organizers of the "Miss Universe" pageant announced the new rule of allowing transgender women to participate in the contest beginning in 2013, pageants in some countries like Mexico have responded by announcing their opposition to the measure. 

In one case, pageant called "Nuestra Belleza Mexico" announced via spokesperson, that they would bar the participation of transgender women into competition. "The rules have been followed since 1994 and it will continue in this respect as it has throughout the history of the competition," according to celebrity news website, Celestrellas and Univision.

Jones then affirmed that their stance was related more to adhering to the contest's rules than going against people who were transgender. "All competitors must be female at birth," the organization announced via an electronic statement.

The Miss Universe pageant announced on Tuesday it was changing its rules according to the organization and gay rights group GLAAD.

The decision was the result of an outcry over the disqualification of contestant Jenna Talackova from the upcoming Miss Universe Canada because she was not a "naturally born female", according to Reuters.

Talackova underwent gender reassignment surgery when she was 19. She was allowed to re-enter to the competition after approval from businessman Donald Trump, owner of the Miss Universe organization.

Talackova has documents that identify her as a woman.
