The probability of genotypic identity and probability of a unique genotype (expressions 5 and 7) together have several advantages over other genetic similarity measures. First of all, these two measures depend upon genotype frequencies and not gene frequencies. Secondly, the probability of genotypic identity is weighted thereby avoiding the frequency dependent attributes of other genetic similarity measures. Thirdly, the probability of a unique genotype allows special consideration to the absence or presence of a genotype in a population.
