Hardy Weinburg
No allele can give an advantage
Yes, use the Hardy-Weinburg equilibrium equation.
Hardy-Weinberg Principle.
The Hardy-Weinberg equilibrium is a mathematical model used to predict the frequency of alleles in a population over time, assuming certain conditions are met. It is used by geneticists to study evolution, genetic drift, and natural selection within populations. It helps determine if a population is evolving or if forces such as mutation, gene flow, or genetic drift are affecting allele frequencies.
The statement that allele frequencies remain constant from generation to generation if certain conditions are met presents a condition of the Hardy-Weinberg principle.
p is the value of an allele frequency.
According to the Hardy-Weinberg principle, the frequency of alleles in a population will remain constant from generation to generation as long as equilibrium is maintained through random mating, no gene flow, no genetic drift, no natural selection, and no mutations.
One condition that must exist before the Hardy-Weinberg principle can be applied is a large population size to prevent genetic drift from significantly affecting allele frequencies.
If 91% of the population consists of black sheep, and the black wool allele is dominant, we can assume that all black sheep carry at least one copy of the black wool allele. Therefore, the frequency of the black wool allele in the population is 100%.
This concept is known as the Hardy-Weinberg equilibrium. It states that, in the absence of evolution forces, allele frequencies will remain constant over generations in a population. It can be used to predict the frequencies of different genotypes in a population if certain conditions are met.
The Hardy-Weinberg principle states that both allele and genotype frequencies in a population remain constant-that is, they are in equilibrium-from generation to generation unless specific disturbing influences are introduced. In practice, however, it is impossible to remove such disturbing influences thus making this principle purely theoretical.
