Multiple Choice
Which of the following best describes artificial selection?
A
The movement of genes from one population to another through migration.
B
The natural process by which organisms better adapted to their environment survive and reproduce.
C
The random change in allele frequencies in a population due to chance events.
D
The process by which humans breed organisms for specific traits.
Verified step by step guidance1
Step 1: Begin by understanding the concept of artificial selection. Artificial selection is a process where humans intentionally breed organisms to enhance or develop specific traits. This is different from natural selection, which occurs without human intervention.
Step 2: Compare artificial selection to other evolutionary processes mentioned in the options. For example, gene flow refers to the movement of genes between populations, while genetic drift involves random changes in allele frequencies due to chance events. These are distinct from artificial selection.
Step 3: Recognize that natural selection is a process driven by environmental pressures, where organisms better adapted to their surroundings are more likely to survive and reproduce. This is also different from artificial selection, which is guided by human choice.
Step 4: Focus on the correct description of artificial selection: humans selectively breed organisms to emphasize desired traits, such as faster growth, specific colors, or resistance to diseases.
Step 5: Conclude that the correct answer is: 'The process by which humans breed organisms for specific traits,' as this best describes artificial selection.
