How is allele frequency different than a genotype?Is there more of a dramatic change in the allele frequencies when alleles change in a larger population or when alleles change in a smaller population? Explain. How is allele frequency different than a genotype?

Explanation / Answer
Allele frequency is relative frequency of an allele at a locus on chromosome in a population.
Genotype is the type of allele present in organism that expresses itself as phenotype.
Example
Allele frequency of an allele T can be 60% in population.
Genotype can be expressed as TT or Tt for tall phenotype.
In a smaller population the change in allele frequency is more dramatic. It works through natural selection and genetic drift. Any changes in allele frequency affect a smaller population as small population means lesser genetic diversity. This low diversity can lead to lesser chances of natural selection in drastic condition hence affecting population number badly.
