What is hardy weinberg principle?
Answers
Hardy Weinberg principle governs the factir affecting the population.
It is basedon equation
p2+q2+2pq=1
Here 1 represents that the gene frequency is constant and no evolution is occuring.
p2 represent homozygous dominant AA.
q2 represents homozygous recessive aa.
2pq representa the heterozygous condition Aa.
There are many factors governing this Principle like Gene flow,Genetic drift,migration etc.

Answer:
Explanation:
It states that there would be no change in the relative frequencies of different gene alleles in a gene pool, and therefore no evolution, in a hypothetical population that met five conditions: no mutation, no genetic drift, no immigration or emigration, random mating, and equal reproductive success of all members.
The reality is that these five conditions can never be met in any real population. Therefore, evolution is inevitable, and we can point to the violations of these five conditions as the causes of evolution.
It also shows that the laws of heredity alone do not cause evolution. Even if a certain allele is very rare, it is not destined to become extinct purely because of the laws of heredity, nor is a common allele automatically destined to become more common. Mendelian heredity is not the cause of evolutionary change.
