In the whiptail lizards only females are born generation after generation. There are no males. How is this possible ?

Explanation

### Step-by-Step Solution:

1. **Understanding the Species**: The question refers to whiptail lizards, a species known for having only female individuals in their population.

2. **Identifying the Reproductive Method**: Whiptail lizards reproduce through a process called **parthenogenesis**. This is a form of asexual reproduction where an egg develops into a new individual without fertilization by a male gamete.

3. **Role of Female Gametes**: In parthenogenesis, only the female gamete (egg) is involved. The female gamete undergoes development independently to form a new individual.
