The ______ allele representing the original phenotype is_________ type and the allele ______ is generally the_______ type/allele.

Options

A. Functional, dominant, modified, recessive
B. unmodified, wild, modified, mutant
C. modified, wild unmodified, recessive
D. Both (1) & (2)

Answer

To fill in the blanks in the question, we need to understand the concepts of dominant and recessive alleles in genetics. Let's break down the question step by step:

### Step-by-Step Solution:

1. **Identify the Original Phenotype**:
- The original phenotype is typically represented by the allele that is functional. This means that it is the allele that expresses a trait in its normal form.
- **Fill in the first blank**: The **functional** allele representing the original phenotype.

2. **Determine the Type of the Original Phenotype Allele**:
- The functional allele is usually dominant. This means it can mask the effect of other alleles.
- **Fill in the second blank**: The allele is **dominant** type.

3. **Identify the Modified Allele**:
- The modified allele is generally the one that does not express the original phenotype and is often recessive.
- **Fill in the third blank**: The allele is **modified**.

4. **Determine the Type of the Modified Allele**:
- The modified allele is usually recessive. This means that it only expresses its trait when in a homozygous condition (when two copies of the recessive allele are present).
- **Fill in the fourth blank**: The allele is generally the **recessive** type.

### Final Answer:
The completed sentence is:
"The **functional** allele representing the original phenotype is **dominant** type and the allele **modified** is generally the **recessive** type/allele."
