Worked Solution & Example Answer:Natural selection involves a A random increase in frequency of DNA sequences that increase survival B random decrease in frequency of DNA sequences that decrease survival C non-random increase in frequency of DNA sequences that increase survival D non-random decrease in frequency of DNA sequences that increase survival. - Scottish Highers Biology - Question 5 - 2023
Step 1
Choose the correct definition of natural selection
Answer
Natural selection is defined as a process where organisms better adapted to their environment tend to survive and produce more offspring. This implies a non-random mechanism that favors certain traits over others. Therefore, the correct choice from the options provided is:
C non-random increase in frequency of DNA sequences that increase survival.
