What Is An Example Of Continuous Variation?

What is continuous variation genetics?

Continuous variation is the combined effect of many genes (known as polygenic inheritance) and is often significantly affected by environmental influences..

What is an example of a variation?

The individual members of a species also have differences in characteristics. For example, humans have different coloured eyes, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.

What do you mean by continuous variation?

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. So it is continuous variation. For any species a characteristic that changes gradually over a range of values shows continuous variation.

Is weight nominal or ordinal?

When working with ratio variables, but not interval variables, the ratio of two measurements has a meaningful interpretation. For example, because weight is a ratio variable, a weight of 4 grams is twice as heavy as a weight of 2 grams.

Is eye Colour continuous or discrete?

Eye color is solely considered a discrete variation rather than continuous variation. It is a polygenic, hereditary trait. Since eyecolor is unchangable and, as a variable, contains a finite amount of variance, it is not able to become continuous (in the way that height, weight, and salary are continuous variables).

IS fingerprint a continuous 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). … Continuous variation is usually polygenic and involves multiple genes.

What is an example of genetic variation?

Genetic variation refers to differences in the genetic makeup of individuals in a population. Genetic variation is necessary in natural selection. … Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.

Is age discrete or continuous?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

Is weight discrete or continuous?

The weight of a fire fighter would be an example of a continuous variable; since a fire fighter’s weight could take on any value between 150 and 250 pounds. Suppose we flip a coin and count the number of heads.

Is hair Colour a continuous variation?

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 type of variable is eye Colour?

Certainly, eye color is a nominal variable, since it is multi-valued (blue, green, brown, grey, pink, black), and there is no clear scale on which to fit the different values.

What are the 3 types of genetic variation?

For a given population, there are three sources of variation: mutation, recombination, and immigration of genes.

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 intelligence continuous variation?

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. …

What are the 5 sources of genetic variation?

Genetic Variationmutation.random mating between organisms.random fertilization.crossing over (or recombination) between chromatids of homologous chromosomes during meiosis.

Is blood type discrete or continuous?

Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable.

What is variation and its types?

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

Is eye Colour an example of continuous or discontinuous variation?

A characteristic of any species with only a limited number of possible values shows discontinuous variation. For example: gender (male or female) eye colour.

What are the causes of continuous variation?

Mendel had noticed in his original paper in 1865 that multifactorial inheritance (i.e. the character is influenced by many genes) can generate a continuous variation. Characters influenced by many genes are called polygenic characters. Differences in external environmental conditions also produce continuous variation.

What are the two types of variation?

Like most living organisms, humans show 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 type of data is weight?

Quantitative data is numerical. It’s used to define information that can be counted. Some examples of quantitative data include distance, speed, height, length and weight.
