Mendel's first law of segregation states that during meiosis, homologous chromosomes segregate from one another, which leads to the separation of different alleles into different gametes. This process occurs during meiosis I, when homologous chromosomes pair up and then separate, each going to a different daughter cell. Therefore, option D, segregation of homologous chromosomes during meiosis I, is the mechanism of Mendel's first law of segregation.
