Mythicаl reseаrchers cоnducted а test crоss with flying miniature unicоrns and expected to get 4 categories of unicorns with a phenotypic ratio 1:1:1:1. He counted 129 unicorns with curved wings and ebony body, 125 with curved wings and gray body, 100 with straight wings and gray body and 90 with straight wings and ebony body. The total number of mini unicorns in the new generation is 444. Calculate the chi square (x2) value using the following formula (O = observed, E = expected, Σ = sum): χ² = Σ [ (O – E)² / E Phenotype Observed Number Expected number (O-E)2 (O-E)2/E Curved wings, ebony body 129 Curved wings, gray body 125 Straight wings, gray body 100 Straight wings, ebony body 90 SUM 444 Σ =
