Why was Vincent not named after his father Antonio, but rather his brother Anton?

Vincent was not named after his father, Antonio, but rather his brother Anton because the first son, Vincent’s older brother, was born with defects. This choice reflects the family's belief in genetic superiority and the societal pressures surrounding genetic perfection depicted in the film GATTACA. By naming Vincent after Anton, the family may have intended to signify a break from the disappointment associated with the first son, who did not meet the societal standards for a 'perfect' human being. This decision highlights the importance placed on genetic predisposition in the world of GATTACA, where being genetically engineered for success is highly valued, and the weight of expectations surrounding one’s name is significant.
