Question

the differences seen within and among species such as fur color, eye color, etc.
evolution
gene flow
frequency
genetic drift
speciation
variation
natural selection

Explanation:

We need to identify the term that describes differences within and among species like fur color, eye color. Let's analyze each option:

• Evolution: Change in species over time, not about differences.
• Gene flow: Transfer of genes between populations, not about differences.
• Frequency: Often about allele frequency, not about differences.
• Genetic drift: Random change in allele frequency, not about differences.
• Speciation: Formation of new species, not about differences.
• Variation: Defined as differences within and among species (like fur/eye color differences).
• Natural selection: Process of selection, not about differences.

Answer:

variation (the option with "variation" text)
