The independent assortment happens in the following steps in the meiosis
1. During the Pachytene stage of prophase I of the meiosis one the genes in the homologous chromosomes mixes randomly among each other by a process called crossing over and largely responsible for the variation between the siblings.
2. Metaphase 1 : The random assortment of bivalent takes place.
3. MetaphaeII : The chromosomes move randomly to the equator

Such gametes after fertilization produce offspring with different characters .
The phase that happens only once in meiosis is prophase I, which is characterized by the pairing of homologous chromosomes and the exchange of genetic material through crossing over. This phase is unique to meiosis and does not occur in mitosis.

The longest phase of meiosis is prophase I, which involves chromosome condensation, crossing over, and nuclear envelope breakdown. This phase can be subdivided into early, mid, and late stages, making it the most time-consuming phase in the process of meiosis.
The second phase of meiosis is called meiosis II. It follows meiosis I and begins with cells that have been through the first division. In meiosis II, the sister chromatids are separated, resulting in four haploid daughter cells.
The law of independent assortment is most directly related to the metaphase I stage of meiosis. During metaphase I, homologous chromosomes line up randomly at the equatorial plate, independently of each other, before separating into different daughter cells. This random alignment contributes to the independent assortment of alleles from different genes located on non-homologous chromosomes.

well, "independent chromosomes" would be more like Anaphase I from meiosis; otherwise, it would be generally Anaphase. (it is not chromosomes but chromatids though, in mitotic anaphase.)

The end result of meiosis phase I is two haploid daughter cells, each containing a unique combination of chromosomes due to crossing over and random assortment of homologous chromosomes. These daughter cells have half the number of chromosomes as the original parent cell.
