Which of the following prossess homogametic male

Options

A. Plants
B. Man
C. Insect
D. Birds

Answer

To determine which of the given options represents a homogametic male, we need to understand the concept of homogametic and heterogametic sexes in different organisms.

### Step-by-Step Solution:

1. **Understand Homogametic and Heterogametic Sexes**:
- Homogametic males produce one type of gamete (sperm), while heterogametic males produce two types of gametes (sperm with different sex chromosomes).

2. **Analyze the Options**:
- **Plants**: In many plants, sex determination can be complex, but they do not typically follow the XY or ZW systems like animals.
- **Man (Humans)**: In humans, males are heterogametic with XY sex chromosomes. They produce two types of gametes: X and Y.
- **Insects**: In many insects, males are also heterogametic (e.g., in Drosophila, males are XY).
- **Birds**: In birds, the sex determination system is ZW for females and ZZ for males. Here, males are homogametic because they have two identical sex chromosomes (ZZ).

3. **Identify the Correct Answer**:
- Based on the analysis, the only option where males are homogametic is **birds**. Males have two Z chromosomes (ZZ), producing only one type of gamete.

### Conclusion:
The correct answer is **birds**.
