Human height is an example of continuous variation. It ranges from that of the shortest person in the world to that of the tallest person. Any height is possible between these values. So it is continuous variation.
What is continuous variation and give example?
Continuous variation is the type of genetic variation showing an unbroken range of phenotypes in a population. Generally, measurable characters such as height, weight, and skin color are classic examples of continuous genetic variation.
What are the examples of continuous and discontinuous variation?
Examples of continuous variation include things like a person’s height and weight . Examples of discontinuous variation include a person’s blood group or the color of a species of bird. These variations can exist for two major reasons.
Is hair Colour a continuous variation?
And clearly hair color, skin color and eye color all fall under the definition of a continuous trait , because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.
Is eye Colour an example of continuous or discontinuous variation?
A characteristic of any species with only a limited number of possible values shows discontinuous variation . For example: eye colour.
How do you know if a graph is continuous or discontinuous?
A function being continuous at a point means that the two-sided limit at that point exists and is equal to the function’s value . Point/removable discontinuity is when the two-sided limit exists, but isn’t equal to the function’s value.
What are the 2 types of variation?
If you consider almost any characteristic, you will find differences between various people (or other animals or plants) in a population. There are two forms of variation: continuous and discontinuous variation .
What do you mean by continuous variation?
biology. : variation in which a series of intermediate types connects the extremes — compare quantitative inheritance .
What are the 3 types of variation?
For a given population, there are three sources of variation: mutation, recombination, and immigration of genes .
What are the 4 types of variation?
Examples of types of variation include direct, inverse, joint, and combined variation .
Is Skin Colour discrete or continuous?
Continuous traits are common in humans, who show a wide range of possibilities in characteristics such as height, skin color, learning ability and blood pressure. These traits are frequently seen in agriculture, as well.
Is age a discrete or continuous?
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.
What is the cause of continuous variation?
Differences in external environmental conditions also produce continuous variation. In nature, each character will be influenced by many environmental variables, some tending to increase it, others to decrease it.
Is eye color a continuous variable?
And clearly hair color, skin color and eye color all fall under the definition of a continuous trait , because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.
Is eye color discrete or continuous variation?
Is eye color a discontinuous trait? And clearly hair color, skin color and eye color all fall under the definition of a continuous trait , because even though they dont seem to be affected by the environment, they are definitely polygenic traits and show a gradation, so they’re definitely continuous traits.
What variable is eye Colour?
The ‘eye colour of a pupil’ is an attribute of an individual and is an example of qualitative data; the ‘numbers of pupils with each eye colour’ is a variable consisting of quantitative data .
