True
Explanation:
An allele refer to two alternative forms of the same gene. An allele is a pair of genes found on a given chromosome. Usually, every allelic pair has one which is dominant and one which is recessive.
The dominant allele is expressed while the recessive allele is not expressed.
The colour of the pea plant is controlled by a pair of alleles wherein purple (P) is dominant to white (p).
The expressed colour of the pea plant(phenotype) is dependent on the arrangement of the genes(genotype) of the pea plant.

Explanation:
Receptors are specific molecular components of a biological system with which drugs interact to produce changes in body function. This fundamental event of drug-receptor interaction initiates communication, through signal molecules (first messenger) of great structural and functional diversity, with receptors coupled to ionic channels, to G-proteins, catalytic or regulators of DNA transcription, as well as The integrated support of second messengers. It also mentions certain diseases that arise due to dysfunction of these receptors of the receptor-effector systems, such as the appearance of aberrant receptors or as products of "oncogenes".
