What is generally the modified allele considered to be?
Options
- ADominant allele
- BRecessive allele
- CNeutral allele
- DCo-dominant allele
Correct answer
B. Recessive allele
Step-by-step solution
In the first case, the modified allele is equivalent to the unmodified allele, i.e., it will produce the same phenotype/trait, i.e., result in the transformation of substrate S. Such equivalent allele pairs are very common. But, if the allele produces a non-functional enzyme or no enzyme, the phenotype may be effected. The phenotype/trait will only be dependent on the functioning of the unmodified allele. The unmodified (functioning) allele, which represents the original phenotype is the dominant allele and the mod
