What does discontinuous variation mean in biology?
What does discontinuous variation mean in biology?
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. There are no values in between, so this is discontinuous variation. …
What is discontinuous variation genetics?
In discontinuous variation, a character is found in a population in two or more distinct and separate forms called phenotypes. Such alternative phenotypes are often found to be encoded by the alleles of one gene. A good example is albinism in humans, which concerns phenotypes of the character of skin pigmentation.
What is discontinuous variation GCSE?
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.
Is eye Colour continuous or discontinuous?
Which are examples of discontinuous variation? Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height.
What is discontinuous trait?
Discontinuous traits – traits with only a few possible phenotypes that fall into discrete classes; phenotype is controlled by one or only a few genes (ex.: tall or short pea plants; red, pink or white snapdragon flowers)
Is blood group continuous or discontinuous?
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.
Is Skin Colour continuous or discontinuous?
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 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.
How is a discontinuous variation represented in a graph?
When a continuous variation is represented graphically, it provides a normal distribution curve with a perfect smooth bell shape. No curve is produced in a graphical representation of discontinuous variation. Summary –Continuous vs Discontinuous Variation
Which is a quantitative trait continuous or discontinuous?
Continuous Variation is a quantitative trait that can be measure so it can are represented using a histogram with can group and range the data in order for it to be properly analysed. Discontinuous Variation is a qualitative trait that cannot be measure so a bar chart is more suited to represent this type of data.
Can a blood group be in between discontinuous variation?
blood group or another – you can’t be in between. Such data is called discrete (or categorical) data. Chi-squared statistical calculations work well in this case. Discontinuous variation is controlled by alleles of a single gene or a small number of genes. The
