What are examples of discontinuous variation?
A characteristic of any species with only a limited number of possible values shows 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).
Is eye Colour an example of discontinuous variation?
Which are examples of discontinuous variation? Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height.
Is eye color a 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 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 are the 3 types of discontinuity?
Continuity and Discontinuity of Functions There are three types of discontinuities: Removable, Jump and Infinite.
Is gender continuous or discontinuous?
On purpose, I made it sound distinct that a variable is either discrete or continuous….Variable Reference Table : Few Examples.
| Variable | Variable Type | Variable Scale |
|---|---|---|
| Temperature | Continuous | Interval |
| Length | Continuous | Ratio |
| Product ID in Numbers | Discrete | Nominal |
| Gender | Discrete | Categorical |
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 eye Colour continuous variation?
Previous studies on the genetics of human eye color used broadly-categorized trait information such as ‘blue’, ‘green’, and ‘brown’. However, variation in eye color exists in a continuous grading from the lightest blue to the darkest brown.
Is the hair color a continuous or discontinuous variation?
Genes carry the information for a particular trait, such as hair. An allele is a variation of the gene that determines color, or thickness, or curliness of that hair. Do you develop continually or discontinuous from birth to death?
Which is the best definition of discontinuous variation?
The definition for discontinuous variation are traits that show clear cut and distinct groups, and are ALWAYS determined by 1 or 2 genes (a few, but not necessarily 1 gene), and is MOST OF THE TIME not affected by the environment, though there are exceptions.
How are discontinuous traits different from continuous traits?
Continuous traits are additive, meaning an allele only affects the trait partly. So they don’t have discrete categories e.g. height, intelligence. Discontinuous traits are the opposite. They are usually determined by few genes, and an allele has a discrete phenotype associated with it e.g. blood groups of ABO.
Is the color of facial hair always the same?
The color of a man’s facial hair is usually the same color as the hairs on his arms and chest. Repetitive shaving only changes the quantity of facial hairs a man possesses, not the color of said hairs.
