Which animal can produce eggs but they did not sex?

You're asking about animals that can produce eggs but don't engage in sexual reproduction. This is a common characteristic of some organisms that reproduce through a process called parthenogenesis.

Here's what you need to know:

* Parthenogenesis: A form of asexual reproduction where an egg develops into a new individual without being fertilized by sperm.

* Animals that reproduce through parthenogenesis:

* Some insects: For example, aphids, stick insects, and some species of bees and ants.

* Some reptiles: Some lizards, like the Komodo dragon, can reproduce this way.

* Some fish: For example, the Amazon molly.

* Some amphibians: Some species of salamanders and frogs.

* Some birds: Although rare, a few bird species are known to reproduce parthenogenetically.

Important Note:

While these animals can produce eggs without mating, the eggs are often haploid (containing only half the number of chromosomes). This can result in offspring with reduced genetic diversity, making them more vulnerable to environmental changes.
