Lee Ann has two fish. One is heterozygous for orange color, and the other is homozygous recessive for black color. Lee Ann decides she wants to breed her fish, but she wants to know ahead of time how many fish of each color will hatch.

Which choice below shows the correct alleles for fish color?

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.
