Mendel's law of segregation states that during gamete formation, the two alleles for a gene segregate (separate) from each other so that each gamete carries only one allele for each gene. This segregation occurs during meiosis I when homologous chromosomes, each containing one of the two alleles, separate and migrate to opposite poles of the cell. Therefore, the separation of homologous chromosomes during meiosis I is the aspect that best explains Mendel's law of segregation.
