According to natural selection, what happens to genes that code for traits beneficial to survival?

• A. They are passed on to the next generation
• B. They are discarded
• C. They become mutated
• D. They disappear

Answer: (A)

In natural selection, traits that help survival give individuals a better chance to reproduce, so the genes behind those traits tend to be passed on to more offspring. Those offspring inherit the beneficial alleles, and as this happens across many generations, the gene becomes more common in the population. It’s not about the genes being discarded or disappearing; the process increases their frequency because more individuals with them survive and reproduce. For example, a gene that improves camouflage will lead to more offspring, who inherit that gene, shifting the population’s genetic makeup toward that beneficial variant.
