__ relers to the physical characteristic of an organism while __ refers to the genetic material of an organism. Phenotype; genotype Phenotype; genome Genotype; phenotype Phenotype; cytosine

## Step 1<br />The problem is asking us to identify the correct terms that refer to the physical characteristics of an organism and the genetic material of an organism. <br /><br />## Step 2<br />The term "Phenotype" refers to the observable physical characteristics of an organism. These characteristics are the result of the interaction between the organism's genetic makeup (genotype) and the environment. For example, the color of a person's eyes, their height, and their blood type are all part of their phenotype.<br /><br />## Step 3<br />The term "Genotype" refers to the genetic makeup of an organism. This includes all of the genes that an organism has, regardless of whether they are expressed or not. The genotype is the set of genes that an organism carries, which can be passed on to its offspring.<br /><br />## Step 4<br />The term "Genome" refers to the complete set of genes in an organism. This includes both the genes that are expressed (the phenotype) and those that are not.<br /><br />## Step 5<br />The term "Cytosine" is a type of nitrogenous base found in DNA and RNA. It is not a term that refers to the physical characteristics or genetic material of an organism.
