If one allele for a trait is dominant and the other allele is recessive, which trait will be visible? The dominant allele or the recessive allele?

• Dominant will be visible because it is blocked by the recessive allele.

• Dominant will be visible because it hides or blocks the recessive allele.

• Recessive will be visible because it is blocked by the dominant allele.

• Recessive will be visible because it hides or blocks the dominant allele.
