What are examples of discrete variation?

What are examples of discrete variation?

Discrete variation is either/or and is often caused by the presence or absence of a small number if genes. For example, our ability to “roll” our tongues is determined by just one gene. We can all either roll our tongue or not – there’s nothing in between.

What is discrete variation in humans?

Characteristics controlled by a single gene (one copy inherited from each parent) tend to have phenotypes that fall into separate categories. They show discrete variation. Discrete variation in a group of individuals can be shown using a bar chart.

Which human characteristics is an example of discontinuous variation?

Human blood group is an example of discontinuous variation. In the ABO blood group system, only four blood groups are possible (A, B, AB or O). There are no values in between, so this is discontinuous variation.

Which of the following human characteristics shows discrete variation?

There are two types of variation: continuous and discrete. Discrete variation describes a characteristic that can be separated into distinct categories or groups. Examples of discrete variation include eye colour, fingerprints, blood groups, ability or inability to tongue roll, attached or detached ear-lobes.

Is eye Colour continuous or discrete?

Discrete data is organised in separate categories and is often presented in a bar chart. Examples of types of discrete data include: eye colour, hair colour, number of people in a shop, favourite chocolate bar. These values are distinct.

Is Skin Colour discrete variation?

Two Kinds of Inherited Variation Continuous variations are differences in characteristics that have a range of possible variations, such as height, shoe size, hand span, skin color, hair color, etc. Discrete variations are differences in characteristics that have a definite form, with a limited number of possibilities.

What are some examples of human variation?

Common human variations

Is age continuous or discrete?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

Is eye Colour discrete or continuous?

What are the different types of variation?

Examples of types of variation include direct, inverse, joint, and combined variation.

What causes variation in humans?

Causes of variation Causes of differences between individuals include independent assortment, the exchange of genes (crossing over and recombination) during reproduction (through meiosis) and various mutational events. There are at least three reasons why genetic variation exists between populations.

Is Money discrete or continuous?

Because money comes, in clear steps of one cent, it’s a discrete variable, as well. In theory, the restaurant could make any amount of money. However, the revenue is still discrete. Because we can think of values that are not possible.

Is eye colour discrete or continuous?

What is a direct variation example?

Some examples of direct variation problems in real life: The number of hours you work and the amount of your paycheck. The amount of weight on a spring and the distance the spring will stretch. The speed of a car and the distance traveled in a certain amount of time.
