Answer:
0 : 1 ( black eyed : orange eyed )
Explanation:
When black eyed-Mendelian is crossed with orange-eyed Mendelian, the entire progeny has black eyes. This means that the allele for Black color is dominant to the color for orange color and it masks its effect completely in the next progeny.
BB X bb = Bb ( All black )
So orange Mendelian is a recessive trait and will have genotype bb. When two orange eyed Mendelians are crossed:
bb X bb = bb ( All orange since there is no B allele )
Hence, the phenotypic ratio will be = 0 : 1 ( black eyed : orange eyed )
