Which of the following is correct observation?

#Section 3: Genetics, Cellular and Molecular Biology

  1. Niche partitioning allows for selection of differential patterns of resource usage, which can drive speciation

  2. This narrowing of phenotypes causes a reduction in genetic diversity in a population

  3. Extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype

  4. The phenotypes grade become wide and caused increases the genetic diversity in a population
