Answer: The correct answer fro the Mendel's principle that is described here is Mendel's first law that is Law of segregation.
According to the law of segregation, alleles ( different forms of a gene that correspond to particular trait) are separated from one another during the process of gamete formation. This results in each gamete having single allele for a particular trait and thus it is also called law of purity of gametes.
Thus, by separation of alleles independent of one another it can be concluded that traits are passed from parents to their offspring independent of one another.
