Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
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?
A
Dominant will be visible because it is blocked by the recessive allele.
B
Dominant will be visible because it hides or blocks the recessive allele.
C
Recessive will be visible because it is blocked by the dominant allele.
D
Recessive will be visible because it hides or blocks the dominant allele.
Explanation: 

Detailed explanation-1: -An individual with one dominant and one recessive allele for a gene will have the dominant phenotype.

Detailed explanation-2: -Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Detailed explanation-3: -Indeed, “codominance” is the specific term for a system in which an allele from each homozygote parent combines in the offspring, and the offspring simultaneously demonstrates both phenotypes.

Detailed explanation-4: -In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
