[A]: Neurospora is an ideal genetic material for research.
[R]: Because of its suitability in the studies of genetics contained within it.

Options

A. If both A and R are true and R is the correct explanation of A
B. If both A and R are true but R is not the correct explanation of A
C. If A is true and R is false
D. If both A and R are false

Answer

**Step-by-Step Solution:**

1. **Understanding Neurospora**: Neurospora is a type of fungus, specifically known as red bread mold, with the scientific name Neurospora crassa. It belongs to the phylum Ascomycota.

2. **Role as a Model Organism**: Neurospora crassa is widely used as a model organism in genetic studies. This means that it serves as a representative example for understanding genetic principles.

3. **Haploid Life Cycle**: One of the key features of Neurospora crassa is that it has a haploid life cycle. This means that it has only one set of chromosomes, which simplifies the study of genetic traits and mutations since there is no dominant or recessive allele to consider.

4. **Sequenced Genome**: Neurospora crassa has a completely sequenced genome consisting of seven chromosomes. This allows researchers to easily identify and study specific genes and their functions.

5. **Ease of Genetic Studies**: The combination of a haploid life cycle and a fully sequenced genome makes Neurospora crassa particularly suitable for genetic research. There are no complications from crossing over or genetic recombination, allowing for straightforward analysis.

6. **Historical Context**: The use of Neurospora crassa in genetic studies was pioneered by researchers Edward Tatum and George Beadle, who demonstrated its utility in understanding genetic functions.

7. **Conclusion**: Based on the above points, we can conclude that both statements are true. Statement A asserts that Neurospora is an ideal genetic material for research, and statement R provides the reason that it is suitable for genetic studies due to its characteristics.

**Final Answer**: Both A and R are true, and R is the correct explanation of A.
