The condition in which there are more than two complete set of chromosome is called

Options

A. Aneuploidy
B. Polypoid
C. Monoploidy
D. Haploidy

Answer

To solve the question, "The condition in which there are more than two complete sets of chromosomes is called," we will analyze the options provided and define relevant terms.

### Step-by-Step Solution:

1. **Understanding Ploidy**:
- The term "ploidy" refers to the number of sets of homologous chromosomes in a cell or organism. It is essential to understand this concept to answer the question correctly.

**Hint**: Remember that "ploidy" relates to the number of complete sets of chromosomes.

2. **Analyzing the Options**:
- **Aneuploidy**: This term refers to an abnormal number of chromosomes in a haploid set. It indicates that the organism does not have the normal number of chromosomes. Examples include monosomy (one less chromosome) and trisomy (one extra chromosome). Therefore, this option does not fit the question.

**Hint**: Aneuploidy involves an abnormal number of chromosomes, not more than two complete sets.

- **Polyploidy**: This condition is characterized by having more than two complete sets of chromosomes. It is common in plants and some animal species. This option aligns with the question's requirement.

**Hint**: Polyploidy is the term used when there are multiple complete sets of chromosomes.

- **Monoploidy**: This refers to having only one complete set of chromosomes. It is the opposite of what the question is asking.

**Hint**: Monoploidy means just one set, which is not what we're looking for.

- **Haploidy**: This term indicates having half the number of chromosomes relative to the diploid set. It also does not fit the requirement of having more than two sets.

**Hint**: Haploidy refers to half the number of chromosomes, not multiple sets.

3. **Conclusion**:
- After analyzing all the options, the correct answer to the question is **polyploidy**, as it specifically denotes the condition of having more than two complete sets of chromosomes.

### Final Answer:
The condition in which there are more than two complete sets of chromosomes is called **polyploidy**.
