Question

An allele whose trait only shows up when the dominant allele is absent is called:

  1. Recessive allele

  2. Dominant allele

  3. Hidden allele

  4. Linked gene

hintHint:

Recessive allele is expressed when the dominant allele is absent.

The correct answer is:

Recessive allele


    • Out of a pair of alleles one is dominant over the other.
    • In the presence of the dominant gene the recessive gene does not express itself as in the case of heterozygous organisms.
    • The recessive gene expresses itself only in the absence of the dominant gene as in the homozygous recessive organisms.

    How is incomplete dominance and co-dominance different from a normal Mendelian cross?

    incomplete dominance, only one allele in the genotype is seen in the phenotype.
    In co-dominance, both alleles in the genotype are seen in the phenotype.
