0.09 How many in the population are homozygous dominant? How many people have wet ear wax (This is the dominant phenotype made of BB and Bb genotypes, so you must add p² and 2PQ):
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.
Hardy Weinberg Equilibrium or HWE states that the frequency of occurrence of specific alleles in a population will remain constant from generation to generation until the disturbing factors that drive evolution are absent (such as natural selection, gene pool, genetic drift, or mutations). It is represented by for. ula,
p + q = 1
and
p2 + 2pq + q2
Where p = dominant allele
q = recessive allele
and p2 = Dominant homozygous allele
q2= recessive homozygous
2pq = Dominant heterozygotes
