What societal limitation does Gattaca highlight regarding genetics?

The choice that genetics determines social class reflects a significant theme in Gattaca, where society is depicted as heavily influenced by genetic engineering and selection. In the film, individuals born through natural means, referred to as "invalids," face discrimination and limited opportunities in contrast to genetically engineered "valids," who are designed to possess superior traits. This creates a hierarchical structure where individuals' social standing is often determined by their genetic makeup rather than their abilities or aspirations.

The film illustrates a dystopian reality in which personal worth and societal roles are largely dictated by one's genetic profile, leading to a system where social mobility is hindered by the predetermined status associated with genetics. This exploration of meritocracy versus genetic determinism raises critical questions about identity, freedom, and the ethical implications of genetic manipulation in society.

Other choices, while related to genetic themes, do not encapsulate the societal limitation depicted in Gattaca as effectively. Genetics not predicting intelligence and the notion that genetics are unchangeable speak to the science of genetic determinism rather than societal structures. The idea that genetics dictate career paths, while relevant, does not fully encompass the film's broader commentary on social class and discrimination.
