What is the name for the physical presentation of an organism's genes?

A. Phenotype

B. Species

C. Phylum

D. Genotype

Answer Explanation:

Phenotype is the physical presentation of an organism's genes. In other words, the phenotype is the physical characteristics of the organism. Phenotype is often contrasted with genotype, the genetic makeup of an organism. The genotype of the organism is not visible in its presentation, although some of the characteristics encoded in the genes have to do with physical presentation. A phylum is a group of classes that are closely related. A species is a group of like organisms that are capable of breeding together and producing similar offspring.

Therefore, the Correct Answer is A.
