Read the given statements and select the correct option
Statement 1 : Test cross is used to determine an unknown genotype within one breeding generation
Statement 2 : Test cross is a cross between `F_(1)` hybrid and dominant parent.

Options

A. Both statements 1 and 2 are correct
B. Statement 1 is correct but statement 2 is incorrect
C. Statement 1 is incorrect but statement 2 is correct
D. Both statement 1 and 2 are incorrect

Answer

To analyze the given statements about test crosses, we can break down the information step by step:

### Step 1: Understanding Test Cross
A test cross is a genetic cross used to determine the genotype of an individual with a dominant phenotype but an unknown genotype. This is typically done by crossing the individual with a homozygous recessive individual.

**Hint:** Remember that a test cross helps reveal whether the dominant phenotype individual is homozygous or heterozygous.

### Step 2: Evaluating Statement 1
**Statement 1:** "Test cross is used to determine an unknown genotype within one breeding generation."
- This statement is correct. The test cross effectively allows us to determine the unknown genotype of an organism by observing the phenotypes of the offspring produced in one generation.

**Hint:** Consider how the offspring's phenotypes can indicate the genotype of the parent.

### Step 3: Evaluating Statement 2
**Statement 2:** "Test cross is a cross between F1 hybrid and dominant parent."
- This statement is incorrect. A test cross involves crossing an F1 hybrid with a homozygous recessive parent, not a dominant parent. The purpose is to see how the dominant phenotype segregates when crossed with a recessive phenotype.

**Hint:** Focus on the definition of a test cross and the types of parents involved.

### Step 4: Conclusion
Based on the evaluation:
- Statement 1 is correct.
- Statement 2 is incorrect.

Thus, the correct option is that Statement 1 is true, and Statement 2 is false.

**Final Answer:** Statement 1 is correct, and Statement 2 is incorrect.
