At locus A in mice, the frequency of the A1 allele is 0.3, and the frequency of the A2 allele is 0.7. At locus B, the frequency of the B1 allele is 0.1, and the frequency of the B2 allele is 0.9. The frequency of all four possible gametes is as follows: p(A1B1) = 0.03 p(A1B2) = 0.27 p(A2B1) = 0.07 p(A2B2) = 0.63 Which of the following statements correctly describes linkage equilibrium or disequilibrium between the two loci? a b 0.3 d 0.7 Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. A₁ A₂ The frequencies of the four gametes add up to 1, so the two loci are in linkage equilibrium. B₁ 0.9 B₂ B₁ B₂ 0.1 0.9 The frequency of B1 is independent of whether A1 or A2 is present in the gamete, so the two loci are in linkage equilibrium. The frequency of B1 is not equal to the frequency of A1, so the two loci are in linkage disequilibrium. The frequencies of both A1 and B1 are not equal to 0.5, so the two loci are in linkage disequilibrium. A₁B₁ 0.03 A₂B₂ 0.27 A₂B₁ 0.07 A₂B,₂ 0.63
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.
