a

Expected ratios according to Haldane (1930).

b

a, b, c, and d correspond with Ait:ait, Apv:apv, Pit:pit, and Ppv:ppv, respectively. χ2 > 3.84 (top) and P < 0.05 (bottom, in bold) are significant (no value where expected segregation is 0:00).

c

Phenotype obligate sexual (lacking penetrance of Ait).

d

Reciprocally to 2(F12 × F13).
