in particular , it does n't account for the $ 3:1 $ ratio . for that , we need mendel 's law of segregation . according to the law of segregation , only one of the two gene copies present in an organism is distributed to each gamete ( egg or sperm cell ) that it makes , and the allocation of the gene copies is random .
