The population of chipmunks in the valley contains 240 individuals. When genotyped for the Alu gene the frequency of the Alu-1 allele in that population is 0.7 (this is the value of q in the valley population) ● Another population of chipmunks is found at higher altitude nearby, and their frequency of the Alu-1 allele is 0.20 (q in the higher altitude population). During a severe winter, 60 of the chipmunks from the high-altitude population migrate to the valley in search of food and join the valley population. a) What will be the frequency of the Alu-1 allele in the valley population in the spring? q after migration in the recipient population = b) How much is the change in frequency due to migration? Aq= c) Please comment on the amount of change due to migration in this case; is it large or small and in what direction and propose a reason for both the magnitude and direction of the change
Evolutionary Genetics
Evolution is known as continuous changes that occur to adjust organisms in their changing environment over many generations. Various theories have been proposed to illustrate the origin of life and organic evolution. The most accepted one is the theory of natural selection by Charles Darwin. According to his postulate, organisms undergo a struggle for existence due to overproduction. To survive in nature, they acquire variations. The inheritable variations are selected by nature, and it leads to the survival of the fittest.
Phenotype Frequency
The majority of populations have a certain degree of variation in their genetic pools. Scientists can predict the genetic variation happening over time by measuring the amount of genetic variation in a population and these predictions assist them in gaining important insights into the processes that allow organisms to adapt to the environment or to develop into new species over generations. This process is referred to as the process of evolution.
Hardy Weinberg Equilibrium
The frequencies of allele and genotype were maintained constant from one generation to another due to the absence of other evolutionary forces. It is otherwise called the Hardy Weinberg principle the field of population genetics.
