LEALLEL But Multiple Alleles allow for of the physical expression of a trait Each allele, like the ice cream, has its own version of a trait but when they come together creates new phenotype 3140 OD TYPE Your blood type is a type of __ There are __ alleles (A, B &O) creating __ possible phenotypes of Red Blood Cells (RBCs) Red Blood Cells have __ on their surface. These proteins are called __ Antigens are substances that can trigger an immune response to foreign things in the body.

# Explanation:<br />## Step 1<br />The problem is about the concept of blood types and the role of alleles in determining these types. The alleles mentioned are A, B, and O, which are responsible for the different blood types in humans. <br /><br />## Step 2<br />The problem also refers to the antigens present on the surface of Red Blood Cells (RBCs). These antigens are proteins that can trigger an immune response if they are foreign to the body.<br /><br />## Step 3<br />The problem also mentions the concept of phenotype, which is the physical expression of a trait. In this case, the phenotype is the blood type.<br /><br />## Step 4<br />The problem also refers to the concept of multiple alleles, which allow for a variety of physical expressions of a trait. In this case, the trait is the blood type.<br /><br />## Step 5<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait. In this case, the phenotype is the blood type.<br /><br />## Step 6<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait.

In this case, the phenotype is the blood type.<br /><br />## Step 17<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait. In this case, the phenotype is the blood type.<br /><br />## Step 18<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait. In this case, the phenotype is the blood type.<br /><br />## Step 19<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait. In this case, the phenotype is the blood type.<br /><br />## Step 20<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait. In this case, the phenotype is the blood type.<br /><br />## Step 21<br />The problem also refers to the concept of phenotype, which is the physical expression of a trait.
