What is continuous and discontinuous variation?
In other words, continuous variation is where the different types of variations are distributed on a continuum, while discontinuous variation is where the different types of variations are placed into discrete, individual categories. Examples of continuous variation include things like a person’s height and weight.
What is discontinuous variation BBC Bitesize?
Discontinuous variation is variation that has distinct groups for organisms to belong to. A bar graph is used to represent discontinuous variation. Examples of discontinuous variation are: blood group, eye colour and tongue rolling.
What’s discontinuous variation?
discontinuous variation (qualitative variation) Clearly defined differences in a characteristic that can be observed in a population. Characteristics that are determined by different alleles at a single locus show discontinuous variation, e.g. garden peas are either wrinkled or smooth. Compare continuous variation.
Is left handedness a discontinuous variation?
Discontinuous Variation Tongue rolling, handedness (left or right) and blood groups are examples. You can either roll your tongue or you cannot. There is no in between category.
Which of the following 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. Here are some examples: blood group, sex (male or female), eye color etc.
Is foot size continuous or discontinuous?
4) Shoe size is an example of discontinuous variation whereas foot length is continuous variation.
What is continuous variation ks3?
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. For any species a characteristic that changes gradually over a range of values shows continuous variation. Examples of such characteristics are: height.
How does discontinuous variation differ from continuous variation?
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.
How can you tell the difference between continuous and 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. Continuous variation has a predictable direction, The direction of the discontinuous variation is unpredictable.
IS fingerprint a discontinuous variation?
Your height, weight, finger length and so on, would have changed throughout your life (continuous), but your blood type, earwax type, fingerprints and sex, do not (discontinuous). Like in most examples of discontinuous variation, earwax type is controlled by a single gene with two alleles.
Is eye Colour continuous or discontinuous?
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 causes continuous and discontinuous variation in an organism?
This can be caused by inherited or environmental factors. Variation can be continuous or discontinuous. Continuous and discontinuous variation. Some of the features of the different organisms in a species show continuous variation, and some features show discontinuous variation.
Which is an example of a continuous variation?
For any species, a characteristic that changes gradually over a range of values shows continuous variation. Examples of such characteristics are: Height ranges from that of the shortest person in the world to that of the tallest person. Any height is possible between these two extremes. So it is continuous variation.
What is the definition of variation in biology?
Variation is the differences between individuals within a species. This can be caused by inherited or environmental factors. Variation can be continuous or discontinuous.
What causes variation in features of a species?
Variation is the differences between individuals within a species. This can be caused by inherited or environmental factors. Variation can be continuous or discontinuous. Some of the features of the different organisms in a species show continuous variation, and some features show discontinuous variation.
