Choose the correct statement(s).
I. Triticum aestivum (wheat) is an artificial hexaploid.
II. Triticale is the first man-made cereal crop.
III. Polyploid individuals carry more than two genome.
IV. Atlas-66 is a biofortified wheat crop.

Options

A. I, II and III
B. I and IV
C. II, III and IV
D. Only II

Answer

To determine the correct statements from the given options, let's analyze each statement step by step:

### Step 1: Analyze Statement I
**Statement I:** Triticum aestivum (wheat) is an artificial hexaploid.

- **Explanation:** Triticum aestivum, commonly known as common wheat or bread wheat, is not artificial; it is a natural cultivated species. It is a hexaploid, meaning it has six sets of chromosomes, but it is not man-made. Therefore, this statement is **incorrect**.

### Step 2: Analyze Statement II
**Statement II:** Triticale is the first man-made cereal crop.

- **Explanation:** Triticale is indeed a hybrid of wheat and rye and is recognized as the first man-made cereal crop. This statement is **correct**.

### Step 3: Analyze Statement III
**Statement III:** Polyploid individuals carry more than two genomes.

- **Explanation:** The definition of polyploidy is that it refers to organisms that have more than two complete sets of chromosomes. Therefore, this statement is **correct**.

### Step 4: Analyze Statement IV
**Statement IV:** Atlas-66 is a biofortified wheat crop.

- **Explanation:** Atlas-66 is a variety of wheat that has been biofortified, meaning its nutritional quality has been enhanced, particularly in terms of protein content. Thus, this statement is **correct**.

### Conclusion
Based on the analysis:
- Statement I is **incorrect**.
- Statements II, III, and IV are **correct**.

### Final Answer
The correct statements are: **II, III, and IV**.
