All individuals have two alleles for a given trait. according to mendel's law of segregation, these alleles are passed down one each from both mother and father. they are passed down through gametes from each parent, which are created by the process known as

The correct answer for the fill in the blank is Meiosis.

Meiosis is a type of cell division, which is a typical feature of sexually reproducing organisms. Meiosis takes place during gamete ( reproductive cells like sperms and egg) formation in each parent. The gametes are haploid as they contain half number of chromosomes as compared to parent cell.

According to the Mendel's Law of Segregation, alleles ( different forms of gene)  are passed into each gamete during gamete formation through the process called meiosis.

Thus, Meiosis is the right answer.
