I. A population called the founder generation, consisting of 2000 AA individuals, 2000 Aa individuals, and 6000 aa individuals is established on a remote island. Mating within this population occurs at random, the three genotypes are selectively neutral, and mutations occur at a negligible rate. *help needed for sub questions d-f. a. What are the frequencies of alleles A and a in the founder generation? b. Is the founder generation at Hardy-Weinberg equilibrium? c. What is the frequency of the A allele in the second generation (that is, the generation subsequent to the founder generation)? d. What are the frequencies for the AA, Aa, and aa genotypes in the second generation? e. Is the second generation at Hardy-Weinberg equilibrium? f. What are the frequencies for the AA, Aa, and aa genotypes in the third generation?
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.
