In which of the following monosomic male is found

Options

A. Human
B. Birds
C. Honey bee
D. Grasshopper

Answer

To solve the question of which organism has a monosomic male, we can follow these steps:

### Step 1: Understand the concept of monosomy
Monosomy refers to the condition where there is only one chromosome present from a pair. In the context of sex chromosomes, a monosomic male would have only one sex chromosome instead of the usual two.

### Step 2: Analyze the options provided
The options given are:
1. Human
2. Birds
3. Honey bee
4. Grasshopper

### Step 3: Examine the sex chromosome composition in each option
- **Humans**: Males have one X and one Y chromosome (XY), which means they have a pair of sex chromosomes.
- **Birds**: Males typically have two Z chromosomes (ZZ), indicating they also have a pair of sex chromosomes.
- **Honey bees**: Males are haploid and have only one set of chromosomes, which includes one sex chromosome (X). However, they do not have a pair of sex chromosomes, as they are not diploid.
- **Grasshoppers**: Males have one X chromosome and no Y chromosome (X0). This means they have only one sex chromosome, which is a classic example of monosomy.

### Step 4: Identify the correct answer
Based on the analysis, the organism that has a monosomic male is the **grasshopper**, as it has only one X chromosome and no corresponding Y chromosome.

### Final Answer
The correct option is **grasshopper**.
