Natural selection is the non-random increase in frequency of DNA sequences that increase survival.
Understand the Problem
The question is stating a concept related to natural selection, focusing on how certain DNA sequences that improve survival rates can become more frequent in a population over time. This highlights the process of evolution through differential survival and reproduction.
Answer
Natural selection is the non-random increase in frequency of DNA sequences that increase survival.
Natural selection is the non-random increase in frequency of DNA sequences that increase survival.
Answer for screen readers
Natural selection is the non-random increase in frequency of DNA sequences that increase survival.
More Information
Natural selection operates by favoring the propagation of advantageous genetic traits that improve the chances of survival and reproduction in a given environment, thus increasing their occurrence within a population over generations.
Tips
A common mistake is to conflate natural selection with other forms of selection such as genetic drift, which is random.
