We first check the first parent's possible alleles: OT, Ot, OT, Ot. (Combinations of the 2 O-alleles and T-alleles given).
A similar process is used for the second: OT, Ot, oT, ot
Genotypes: Check the attachment. We combine the alleles from each parent (for example, Ot + oT = OoTt). We do this for all 16 combinations.
Genotype Likelihoods: We count each of the possible results and tabulate the number of times each appears, and divide by the total number of combinations (16).
OOTT: 2/16 = 1/8 = 0.125
OOTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
OoTT: 2/16 = 1/8 = 0.125
OoTt: 4/16 = 1/4 = 0.25
Oott: 2/16 = 1/8 = 0.125
Phenotypes: Check attachment. Based on the genotypes, use the dominant gene if at least one is dominant (Ex. Oo = O, oo = o)
Phenotype Likelihoods: We count the number of each possibility, only 2 of which are present: OT and Ot, then divide by the total number of combinations, which is 16.
OT: 12/16 = 3/4 = 0.75
Ot: 4/16 = 1/4 = 0.25
