The soul's past experience determines the karma that it needs to work out, but the soul has many choices in deciding how to resolve that karma and forever to do it. The soul also chooses new experiences and situations to face. In choosing the body, some of the important considerations are the hereditary pattern in the genes, the probable environment of nurturing and upbringing, and the likely relationships with other souls. Since all spirits in the universe are free, most of these factors can only be calculated in probabilities.
