Genetic diversity and Natural selection

• What is genetic diversity?

  is the number of different alleles of each gene in a population
• What is a phenotype?

  Is an expression of the genotype and its interaction with the environment
• Describe the process of natural selection

  • random mutation results in new allele of a gene
  • leads to increased reproductive success
  • over many generations, frequency of allele increases
• What is stabilising selection?

  a type of natural selection in which the intermediate phenotype is favoured
• What is directional selection?

  is a type of natural selection in which one extreme phenotype is favoured
