M	F	O exclusion	Comment
BB	NA	AAA, AAB	Father has missing genotype and mother is homozygous
AA	NA	ABB, BBB	Father has missing genotype and mother is homozygous
NA	AA	BBB	Mother has missing genotype and father is homozygous
NA	BB	AAA	Mother has missing genotype and father is homozygous
AA	BB	AAA, ABB, BBB	Oppositely homozygous parents
BB	AA	AAA, AAB, BBB	Oppositely homozygous parents
AA	AA	AAB, ABB, BBB	Identically homozygous parents
BB	BB	AAA, AAB, ABB	Identically homozygous parents
AA	AB	ABB, BBB	Mother homozygous, father heterozygous
BB	AB	AAA, AAB	Mother homozygous, father heterozygous
AB	AA	BBB	Mother heterozygous, father homozygous
AB	BB	AAA	Mother heterozygous, father homozygous

NA indicates missing genotype
