A duplicate of holotype is called :–

Options

A. Isotype
B. Syntype
C. Neotype
D. Paratype

Answer

To solve the question "A duplicate of holotype is called:", we can follow these steps:

### Step 1: Understand the term "holotype"
A holotype is a single physical example of an organism that is used to formally describe a species. It serves as the definitive example of that species.

**Hint:** Think of a holotype as the original specimen that defines a species.

### Step 2: Identify what a duplicate of a holotype is called
When a duplicate of a holotype is created, particularly in the context of plants, it is referred to as an "isotype." This means that isotypes are duplicates of the original holotype specimen.

**Hint:** Consider the term "isotype" as it relates to the duplication of the original specimen.

### Step 3: Review the other options
The other options provided are syntype, neotype, and paratype.
- **Syntype** refers to any one of two or more specimens cited when no holotype was designated.
- **Neotype** is a specimen selected to serve as a type when the holotype is lost or destroyed.
- **Paratype** refers to specimens that are not the holotype but are used to help define the species.

**Hint:** Differentiate between the terms based on their definitions and roles in taxonomy.

### Step 4: Conclude the answer
Based on the definitions and the understanding of the terms, the correct answer to the question is "isotype."

**Final Answer:** A duplicate of holotype is called an **isotype**.
