According to law of independent assortment, the alleles were not bound to remain in
parental combination forever, rather these were free to assort independently .
A could go with B or b in any gamete with equal change.
B could go with A or a in any gamete with equal probability. Four types of gametes, i.e., AB, Ab, aB and ab were formed in equal number in a perfect ratio of 1:1 : 1:1.
