In Lacerta saxicola armaniaca (lizard) there are

Options

A. females only
B. males only
C. bisexual only
D. Both (1) and (2)

Answer

### Step-by-Step Solution:

1. **Identify the Organism**: The question refers to *Lacerta saxicola armeniaca*, which is a type of lizard.

2. **Classify the Organism**: This lizard belongs to the class Reptilia. Reptiles are known for their specific reproductive strategies.

3. **Understand Reproductive Modes**: Reproduction in organisms can occur through two primary modes: sexual and asexual reproduction.

- **Sexual Reproduction**: Involves the fusion of male and female gametes (sperm and egg) to form a zygote. The egg cell and sperm cell are both haploid, and their fusion results in a diploid zygote.

- **Asexual Reproduction**: Involves reproduction without the fusion of gametes. A diploid organism can divide to produce another diploid organism.

4. **Introduce Parthenogenesis**: There is a special form of asexual reproduction known as parthenogenesis. In this process, a female can produce offspring without fertilization.

- In parthenogenesis, the female produces an ovum (haploid), which can develop into a zygote without the need for sperm. This zygote will also be haploid and will develop into an organism that is genetically similar to the mother.

5. **Determine the Offspring Characteristics**: In the case of *Lacerta saxicola armeniaca*, if parthenogenesis occurs, the offspring produced will be females. This is because the zygote formed from the ovum will carry the genetic material of the female only.

6. **Conclude the Answer**: Therefore, the answer to the question is that in *Lacerta saxicola armeniaca*, there are females only when reproduction occurs through parthenogenesis.

### Final Answer:
In *Lacerta saxicola armeniaca*, there are females only.
