Answer:
The correct option is A) O→ orange, o→ black
Explanation:
A dominant allele can be described as the allele which masks the effect of a recessive allele. A recessive allele can be described as the allele whose effect gets suppressed by the dominant allele. A dominant allele is written with a capital letter whereas a recessive allele is referred with a small letter.
As the option A shows capital letter, O, for the dominant orange trait and small letter, o , for the recessive black trait hence, it is the correct option.
