Question

When a genotype consists of a dominant and a recessive allele for a trait, the phenotype expressed will be .

• A. dominant
• B. recessive
• C. new
• D. incomplete

Answer 1

The correct option is A dominant

Every gene has two alternative forms for a character, which produces two different variations of the trait. These alternative forms of the genes are called alleles.
Alleles are of two types based on their expression in the presence of each other - dominant and recessive. The allele that expresses itself while masking the effect of the other is called dominant allele. The allele that fails to express itself in the presence of the dominant allele is called a recessive allele.
