What was the purpose of hardy and weinberg’s work

The letter B is the right answer.

Explanation:

The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.

In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.

According to this law, the necessary conditions for a population to reach equilibrium are:

a) The population must be large, so that all possible intersections occur.

b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.

Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
