In simple dominance, what is the result when a dominant allele pairs up with a recessive allele?

Offspring display both forms of the trait.

Offspring display an intermediate form of the trait.

The dominant form of the trait shows.

The recessive form of the trait shows.

Option C, The dominant form of the trait shows

Explanation:

In simple dominance the trait associated with the dominant allele is expressed while the trait associated with the recessive allele is oppressed. For example -

Let's assume a flower in which the dominant allele trait is red color and the recessive allele trait is white color. When an offspring of this flower is produced containing one dominant allele and one recessive allele, the color of it would be red only because only the dominant allele expresses its trait.

Hence the correct answer is option C

In most cases, the dominant form of the trait shows.
