Is heart rate 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.

What are examples of discontinuous variation?

Human blood groups are an example of discontinuous variation. In the ABO blood group system, only four blood groups are possible - A, B, AB or O. You cannot have a blood group in between these four groups, so this is discontinuous variation.

How do you distinguish between continuous and discontinuous 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.

What is discontinuous variation?

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

What is continuous and discontinuous traits?

If a characteristic can change gradually, it is continuous. If it can only jump from one category to the next, it's discontinuous.

Continuous and Discontinuous Variation | A-level Biology | OCR, AQA, Edexcel

Is blood type 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.

Is weight a discontinuous variation?

For any species, a characteristic that changes gradually over a range of values shows continuous variation. Examples of such characteristics are: height. weight.

Is eye color continuous or discontinuous?

Discontinuous: Eye colour, handedness & lobed/lobeless ears. Continuous: Hand span, arm length & height.

Is tongue rolling continuous or discontinuous?

The ability to roll the tongue, and blood groups, are examples of discontinuous variation.

Is skin color continuous or discontinuous variation?

Explanation: 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 body mass continuous or discontinuous?

Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.

Is shoe size discontinuous variation?

4) Shoe size is an example of discontinuous variation whereas foot length is continuous variation.

Why is continuous variation common in humans?

Answer and Explanation: The traits such as height in humans show continuous variation because these continuous traits show a range of expressions and are under polygenic... See full answer below.

Is hair type continuous or discontinuous?

Continuous variation is the opposite, and these are genetic traits that change, like height, hair colour, shoe size. Examples in humans would be a phenotype with distinct categories where there is no variation over time.

Is number of fingers 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.

Is IQ continuous or discontinuous?

Those characteristics that are determined by the joint action of many genes, and intelligence and stature are two examples, are called quantitative characters because they are measured on a continuous scale.

IS fingerprint continuous variation?

Fingerprint: This is a type of discontinuous variation whereby each human being has a fingerprint that is specific to that person. This is due to slight variation in the main groups of the fingerprints. Fingerprints are impressions of the ridge on the ends of our fingers and thumbs.

What is a discontinuous trait?

Definitions. 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 height continuous or discrete?

Height, weight, temperature and length are all examples of continuous data.

Is hair color continuous or discrete?

Hair colour is a type of discrete data because the values are distinct. You either have one hair colour or another! Continuous data covers a range, so each category is not separate but runs into the next.

Why is skin color a continuous variation?

Genetics of Skin Color

Different populations have different frequencies of the alleles. The combined effects of the alleles bring about the complex, continuous variation in skin color in the human species worldwide.

Is wool production in sheep continuous or discontinuous?

Wool growth is continuous and fibre diameters are more uniform, with P/S fibre diameter (Dp/Ds) ratios ranging from 1.0 to 1.3 (Carter, 1968).

What causes continuous and 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. In continuous variation there is a complete range of measurements from one extreme to the other.

Why are blood groups considered an example 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). There are no values in between, so this is discontinuous variation.
