A population consists of 7 mice. For the coat color trait, there are only two alleles: brown (B) and white (b). BB and Bb mice are brown; bb mice are white. In the population's gene pool, there are 7 white alleles (b). a) What is the frequency of the brown allele in the population? ISelect) b) What do you predict the frequency of the bb genotype will be in the next generation if no evolution takes place in the population? I Select) C) The mice live on dark black, volcanic rocks in the Arizona desert and two hawks are introduced into the area as part of wildlife rehabilitation program. You sample the mouse population after the hawk reintroduction and find the following numbers: 24 BB mice, 52 Bb mice, 24 bb mice. Has natural selection by the hawks caused the population to evolve significantly? (Select)
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.
