How does Vincent attempt to overcome his genetic disadvantages?

Vincent's strategy to overcome his genetic disadvantages primarily involves the use of alternative identities. In the world of "GATTACA," where genetic profiling determines an individual’s social value and opportunities, Vincent is genetically engineered to be inferior to those deemed "valid." To navigate this biased society, he assumes the identity of a genetically elite individual named Jerome Morrow, who provides his DNA for Vincent to use. This allows Vincent to circumvent the genetic discrimination he faces and pursue his dream of space travel, demonstrating resourcefulness and determination in a society that strictly judges individuals based on their DNA.

While other methods such as modifying DNA or using performance-enhancing drugs might seem like potential avenues for overcoming genetic limitations, Vincent does not resort to these means. His primary focus is on identity and deception, allowing him to integrate into a system that would otherwise prevent him from achieving his goals. Thus, the use of alternative identities is a key aspect of his journey and illustrates the lengths to which Vincent goes in order to prove that he is more than just his genetic makeup.
