Answer:
The result of the following cross indicates the orange eyes are recessive to black eyes
Step-by-step explanation:
According to Mendel, a cross involving two individuals that are heterozygous for a dominant trait will yield offspring in the phenotype ratio 3:1 with the dominant trait accounting for about 75% of the phenotype and the recessive trait accounting for the remaining 25%.
In this case, black eye colour phenotype is 247 while orange eye colour phenotype is 86.
Calculating the percentage for each trait
Black eye = 247/333 x 100% = 74.1%
Orange eye = 86/333 x 100% = 25.8%
74.1:25.8 is approximately 3:1
Hence, it is obvious that the orange eyes are recessive while the black eyes are dominant.
