Explanation:

The allele that an organism inherits from its parents influence its phenotype. Phenotypes can also be influenced throughout an organism’s lifetime by changing the expression of particular genes. For example, increasing the expression of an allele will often accentuate that allele’s phenotype.

Allele represents the alternate form of a gene. Hence, the allele inherited determines the phenotype of an organism.

The physical appearance of an organism is also influenced by gene regulation. A gene can be turn on/off as the the case may be and this will affect the phenotype.

Increasing the expression of an allele will accentuate or emphasize the phenotype the allele controls and vice versa.
