Why is "fitness" in selection referred to "relative fitness"? Group of answer choices A_"Relative fitness" refers to fitness of a genotype relative to the environment that organisms are in B_"Relative fitness" refers to fitness of some genotypes relative to other genotypes in a population
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.
Why is "fitness" in selection referred to "relative fitness"?
A_"Relative fitness" refers to fitness of a genotype relative to the environment that organisms are in
B_"Relative fitness" refers to fitness of some genotypes relative to other genotypes in a population
The change in the heritable characteristics of the species across many generations is called evolution. Evolution is a gradual process, and according to the theory of evolution, all species are related and evolved gradually.
In population genetics principles, fitness is the quantitative description of natural and sexual selection in evolutionary biology. Fitness represents individual reproductive success and is equal to the average addition to the gene pool of the subsequent generation that is produced by individuals of the defined genotype or phenotype.
