Correct answer is (b) The alleles separate during meiosis and pair up during fertilization

Best explanation: The second law of Mendel is the law of segregation. It states that the alleles are segregated during the process of meiosis and these pair again after fertilization to restore the genetic composition. This explains the loss of recessive phenotype in F1 and reappearance of it in F2 generation.
