In a stabilizing selection scenario, which phenotypes in the population are selected against over geological time?

A. Only the most common intermediate phenotypes
B. Both phenotypic extremes of the distribution curve
✓
C. Only the recessive phenotypic traits
D. The phenotypes of the oldest individuals in the population

📝 Explanation

Stabilizing selection favors intermediate variants by acting against extreme phenotypes, reducing variation and maintaining the status quo of a phenotypic trait.

📖 Additional Information

  • Only the most common intermediate phenotypes
  • Both phenotypic extremes of the distribution curve
  • Only the recessive phenotypic traits
  • The phenotypes of the oldest individuals in the population

Stabilizing selection favors intermediate variants by acting against extreme phenotypes, reducing variation and maintaining the status quo of a phenotypic trait.
