Genetics

"Genetics" is a song by Meghan Trainor that was recorded for her Treat Myself album, but did not make the cut. A demo version of the track leaked in early 2019, and the final version was released in September 2019 as a single for the Netflix movie Tall Girl. A remixed version featuring The Pussycat Dolls appears on the album.

Background
In December 2018, Meghan said in an interview for Billboard that she wanted the song to be her next single.

A demo version of the song leaked in March of 2019 along with another then-unreleased track of Trainor's, Say It to My Face. The song was finally released on September 13th, 2019 as a single for Netflix's Tall Girl movie.
