Two crosses between the same pair of genotype or phenotypes in which the sources of the gametes are reversed in one cross, is known as

Options

A. back cross
B. dihybrid cross
C. test cross
D. reciprocal cross

Answer

To solve the question, "Two crosses between the same pair of genotype or phenotypes in which the sources of the gametes are reversed in one cross, is known as," we can follow these steps:

### Step 1: Understand the Terminology
- **Genotype** refers to the genetic makeup of an organism.
- **Phenotype** refers to the observable traits or characteristics of an organism.
- **Gametes** are the reproductive cells (sperm and egg) that combine during fertilization.

### Step 2: Identify the Types of Crosses
- **Back Cross**: This involves crossing an offspring with one of its parents.
- **Dihybrid Cross**: This involves two different traits (e.g., height and color).
- **Test Cross**: This is a cross between an individual with an unknown genotype and a homozygous recessive individual.
- **Reciprocal Cross**: This is the cross between the same pair of genotypes or phenotypes, where the sources of the gametes are reversed in one of the crosses.

### Step 3: Analyze the Question
The question specifies that the two crosses involve the same pair of genotypes or phenotypes, and that the sources of the gametes are reversed in one of the crosses.

### Step 4: Identify the Correct Answer
Based on the definitions and the analysis, the correct term for this type of cross is **Reciprocal Cross**.

### Final Answer
The answer to the question is **Reciprocal Cross**.
