Stabilizing selection

Step-by-step explanation:

  • Stabilizing selection is a type of natural selection which favours the intermediate genotype and eliminates extreme genotypes (inferior and superior)
  • Cardinals produce an average of six eggs in each clutch,here production of six eggs represents intermediate genotype

  • If there are fewer than six eggs then this represents inferior phenotype,where predators may destroy the entire clutch
