As you may have found, population-based patterns can be found in the genotypes of particular genes. We did this exercise on a ha
Nikolay [14]
In diseases, similar patterns of mutations in harmless genes may possibly be a cause or an effect of the disease. To investigate if it is a cause, it is worth looking into the proteins synthesized by the gene and whether it’s structure or functionality is affected by the pattern observed. It is also worth looking into the downstream effects possibly caused by the pattern in the gene. The gene may encode a non coding region which could affect post transcriptional splicing for example.

1. What is meant by allele frequency?
rewona [7]

Allele frequency

Explanation:

  • It is a comparative recurrence of an allele on a genetic locus in a population.
  • It is expressed in terms of percentage, decimal or fraction.
  • The variety of a species population genetics is given by Allele frequency.
  • It represents the incidence of a gene variant in a population.
  • It is calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population.
  • Allele frequency is a reflection of genetic diversity.
