What is the definition of discontinuous variation?

What is the definition of discontinuous variation?

Definition of discontinuous variation biology. : abrupt variation in which there are few or no intermediate forms.

What are continuous and discontinuous traits?

The main difference between continuous and discontinuous variation is that continuous variation shows an unbroken range of phenotypes of a particular character in the population whereas discontinuous variation shows two or more separate forms of a character in the population.

What’s the difference between continuous and discontinuous data?

Discrete data is information that can only take certain values. Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

Is eye Colour continuous or discontinuous variation?

Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height. Discontinuous data can be plotted on a bar chart. For example, a person can only have one of four blood groups – A, B, AB or O.

What is discontinuous variation caused by?

Discontinuous variation is controlled by alleles of a single gene or a small number of genes. The environment has little effect on this type of variation. In continuous variation there is a complete range of measurements from one extreme to the other.

Is weight discontinuous variation?

Discontinuous variation refers to things like eye colour or blood group, which have a limited number of possible values. Continuous variation refers to characteristics like weight or height, which change gradually. A person’s height could measure any value in between the shortest and tallest person in the world.

What causes discontinuous variation?

Discontinuous variation is controlled by alleles of a single gene or a small number of genes. The environment has little effect on this type of variation. Continuous variation is the combined effect of many genes (known as polygenic inheritance) and is often significantly affected by environmental influences.

What is continuous variation example?

continuous variation An assemblage of measurements of a phenotypic character which form a continuous spectrum of values. Examples are body weight, height, or shape, reproductive rate, and various behaviour traits.

What is an example of discontinuous variation?

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. They could be purely random genetic changes, or they can be traits that have been influenced and selected by the environment.

Is gender continuous or discontinuous?

Gender is also discontinuous. You’re either male or female. Human blood groups are another great example of discontinuous (discrete) variation. There are only four possible distinct blood groups.

Is finger length continuous or discontinuous variation?

Examples of continuous variation include height, weight, heart rate, finger length, leaf length, etc. Examples of discontinuous variation include tongue rolling, finger prints, eye colour, and blood groups. Continuous variation fluctuates around an average or a mean of species.

Is earlobe shape continuous or discontinuous?

Here, when you organize your ear cards into a continuous spectrum, you’re describing earlobe shape as a continuous trait, ranging from free to attached. Scientists usually consider continuous traits to be complex traits.

What is the difference between continuous variation and discontinuous variation?

Continuous vs Discontinuous Variation. Continuous variation is a variation that has no limit on the value that can occur within a population. Discontinuous variation is a variation that has distinct groups for organisms to belong to.

What effect does the environment have on discontinuous variation?

The environment has little effect on this type of variation. Discontinuous variation refers to the type of genetic variation, which shows two or more separate forms of a character in the population. Discontinuous variations are the main factor in developing continuous variations as well as in the process of evolution.

What is variation and its types?

Variations are the different characteristics that exist in organisms of a natural population or species. Variations can be of two different forms: continuous variation and discontinuous variation. The two forms of variation contain many differences. Discontinuous variation is a cooperating factor in the process of evolution.

Is ABO a continuous or a discontinuous variation?

In human blood group system, only four blood groups are possible (A, B, AB, and O). Since no intermediate values are present for the human ABO blood group system, it is considered as a discontinuous variation. Discontinuous variations are decided by a single gene or a small number of genes.
