Select the INCORRECT statement regarding stabilizing selection.
- AIt acquires mean character value.
- BTends to eliminate both the phenotypic extremes.
- CPopulation is adapted to its environment.
- Correct answerDThis kind of selection is seen in African seed cracker finches.
Solution
Stabilizing selection operates when phenotypic features coincide with optimal environmental conditions. It favors the intermediate or mean character value and eliminates both phenotypic extremes, keeping the population adapted to its stable environment.
African seed cracker finches exhibit disruptive selection, not stabilizing selection. In this population, birds with either large or small beaks are favored over those with intermediate-sized beaks because they specialize in cracking hard and soft seeds, respectively.
Answer: This kind of selection is seen in African seed cracker finches.
