Question

What is Hardy Weinberg law?

Answer 1

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.

Answer 2

Reaction:-

p² + 2pq + q² = 1 (A-->p,a-->q,p+q=q)

In this equation,

1. Fequency of A-->P or the Frequency of Homozygous dominant will be AA-P².

2. In this equation frequency of a-->q the frequency of homozygous recessive - q² the trequency of Aa = 2pq.

3. The frequency of different genotype produced due to random mating will depend upon the gene frequency.

4. Equilibrium is stablished after one single generation ot random mating.
