Question
An allele whose trait only shows up when the dominant allele is absent is called:
Recessive allele
Dominant allele
Hidden allele
Linked gene
Recessive allele
Dominant allele
Hidden allele
Linked gene
Hint:
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.
