In a certain population, D is a dominant, wild-type allele of a gene encoding a protein important for cell division, and d is a recessive, loss- of-function allele of that gene. The allele frequencies for this gene in this popoulation are D = .7, d = .3 If mutation is the only force acting on this population from generation to generation, what do you predict will happen to allele frequencies over successive generations?

Respuesta :

The frequency of the d allele will increase over successive generations.

The number of times the allele of interest is observed in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to calculate the allele frequency. The frequency of alleles can be expressed as a decimal, a percentage, or a fraction.

The relative genotype frequencies depict the genetic variation distribution in a population. The percentage of all copies of a specific gene in a population that carry a specific allele is known as relative allele frequency. The mechanisms that cause changes in allele frequencies over time are natural selection, genetic drift, and gene flow. When one or more of these forces act in a population, the Hardy-Weinberg assumptions are violated, and evolution occurs.
