What is Mendel's second law?
Mendel's second law postulates that two or more different traits are also conditioned by two or more pair of dissimilar factors and that each inherited pair divides independently from the others. In other words, gametes are produced always with an aleatory representative of every pair of the factors that determine phenotypical characteristics.
Mendel's second law is also known as the law of independent segregation of factors, or law of independent assortment.
