Similarly, let p A B {\displaystyle p_{AB}} be the frequency with which both A and B occur together in the same gamete (i.e. p A B {\displaystyle p_{AB}} is the frequency of the AB haplotype).
De xeito similar, sexa p A B {\displaystyle p_{AB}} a frecuencia de aparición de A e B xuntos no mesmo gameto (é dicir, p A B {\displaystyle p_{AB}} é a frecuencia do haplotipo AB).
