What is the equation? - Answer The equation is p2 + 2pq + q2 = 1
What does this principle mean? - Answer This principle means that the combined
frequencies of all alleles for a gene in a population must equal 1. The hardy principle
tells us that something other than the reshuffling processes of sexual reproduction is
required to change allele frequencies in a population
Name and explain 3 applications for this principle. - Answer -Very large population: the
smaller the population, the more likely that allele frequencies will fluctuate by chance
from one generation to the next.
-No gene flow between parents: When individuals move into or out of populations, they
add or remove alleles, altering the gene pool.
- No mutations: By changing alleles or deleting or duplicating genes, mutations modify
the gene pool
How does this play a role in what we have learned about evolution and populations? -
Answer We learned how to estimate the amount of people that carry alleles for a certain
disease. We can calculate the frequencies of alleles in populations and we can also
estimate what frequencies will be in the next generation.
What can it do? - Answer It can determine whether population is devolving; they can
also track diseases in population
What do the components of the equation stand for? - Answer Frequency of
homozygous dominants + frequency of heterozygotes + Frequency of homozygous
recessive =
