Answer:
genotype; phenotype
Step-by-step explanation:
Genotype is the array of genes that an organism carries. Whereas, the phenotype is all of the observable characteristics of an organism and are influenced both by the environment and its genotype. The genotype is defined as the set of genes present in our DNA and is responsible for a particular pattern or trait. The phenotype is the characteristics of the physical expression of that particular trait.
Example: Two different organisms having a minute difference in their genes possess or carry different genotypes such as hair color, eye color, heights, etc.
