Answer:
a. the result of an individual's genetic constitution
Explanation:
Phenotype is the morphological expression of genotype. The genetic constituent of an individual is known as genotype. Genotype determines the genetic traits and imparts specific features of the organisms which constitute the phenotype of the organism.
The phenotype of the organisms depends on the type of the alleles of the genes present in the genome of the organisms.
For example, a human with genotype "ii" has blood type "O". Here, "ii" is the genotype that is responsible for phenotype "O blood type".
On the other hand, a human with genotype "IAIA" has blood type "A". Here. "blood type A" is the phenotype.
Answer:
Organism D.
Explanation:
Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.
The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.
Thus, the answer is organism D.
