What are differences in animals called?

Differences in animals are called variation. This variation can occur in many ways, including:

* Physical traits: This includes differences in size, shape, color, markings, and even the number of limbs or teeth.

* Behavioral traits: This includes differences in how animals act, such as how they find food, communicate, or raise their young.

* Genetic traits: This refers to the differences in the underlying DNA that makes up an animal.

Here are some specific terms used to describe different types of variation:

* Phenotypic variation: This refers to the observable differences in an animal's physical traits or behavior.

* Genotypic variation: This refers to the differences in an animal's genetic makeup.

* Heritable variation: This refers to differences that can be passed down from parents to offspring.

* Non-heritable variation: This refers to differences that are not caused by genetics, such as those caused by environmental factors.

It's important to remember that variation is essential for the survival of a species. It allows populations to adapt to changing environments and increases the chances that some individuals will survive and reproduce even in the face of challenges.
