Fig 1.
The pedigree tree for all four pedigrees.
(A) family 1; (B) family 3; (C) family 2 and (D) family 4. The numeric number denotes the individual IDs. The circles denote females and the squares denote males. Individuals who observed blue and black were labeled in blue; individuals who observed white and gold were labeled in yellow. White color denotes missing data. The slash denotes decease. AA, Aa or aa was hypothesized genotypes under the assumption that the ability of observing blue-black colors from the dress picture was controlled by an autosomal locus with alleles A and a where a was the recessive allele.
