Answer:

The main reason for the production of haploid cells during meiosis is because the two haploid cells will fuse together to make a new genetically different diploid cell  that will form the offspring.

Explanation:

In the context of sexual reproduction, meiosis is the process of cell division by which gametogenesis occurs. In this process, diploid cells are used to obtain haploid cells, called gametes.

The reduction of the chromosomal charge that occurs in meiosis is aimed at producing haploid cells —with half of the crosmosomes of a species— so that <u>when the parents' gametes join, they form a diploide cell</u> called zygote.

The zygote is the starting point for the development of a new individual, part of the offspring.
