Which of the following alleles would most likely be in Hardy Weinberg equilibrium? An allele in a population of cichlid fishes that codes for stronger more streamlined fins An allele for muscle mass in male gorillas which allows them to better compete for females An allele in a population of squirrels that causes them to have fir between their paws and has no effect on their survival and reproduction An allele in a population of peacocks that codes for brighter tales in males
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.
There are found following Hardy Weinberg assumption:
- There are not found any migration between the individuals between two population.
- There are not found any mutation in the gene which is found in this equilibrium.
- There are not found any selection for a particular trait in the population.
- There are found random mating between the individuals.
