What is an example of discrete variation?

Discrete variation is either/or and is often caused by the presence or absence of a small number if genes. For example, our ability to "roll" our tongues is determined by just one gene. We can all either roll our tongue or not - there's nothing in between.

What is discrete variations?

Definition. Continuous variation refers to the type of genetic variation, which shows an unbroken range of phenotypes of a particular character in the population while discontinuous variation refers to the type of genetic variation, which shows to or more separate forms of a character in the population.

What is an example of a discrete trait?

Discrete traits, which are not common in humans, include widow's peak and cleft chin. Certain medical conditions are also discrete, such as cystic fibrosis and Huntington's disease.

Is eye color an example of discrete variation?

Which are examples of discontinuous variation? Discontinuous: Eye colour, handedness & lobed/lobeless ears.

Is gender a discrete variation?

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.

Discrete vs. Continuous Relationships Tutorial

Is height continuous or discrete?

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

Is eye colour discrete or continuous?

Discrete data is organised in separate categories and is often presented in a bar chart. Examples of types of discrete data include: eye colour, hair colour, number of people in a shop, favourite chocolate bar. These values are distinct.

Is arm span a discrete variation?

So, a characteristic that changes gradually over a range of values shows continuous variation. Examples of such characteristics are: height. arm span.

Is tongue rolling a discontinuous variation?

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

Is eye color a discrete trait?

Genetic determination of eye color

It was originally thought that eye color was a simple Mendelian trait, meaning it was determined by a single gene, with brown being dominant and blue recessive. It is now clear that eye color is a polygenic trait, meaning it is determined by multiple genes.

Is skin color discrete?

The darkest skin is due to six dominant “doses” and the lightest skin is due to six recessive “doses”. Varying combinations of the alleles result in seven discrete colors. Mendel's laws (reviewed in slides) show that there are different combinations of the three expressed genes for each of the seven colors.

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.

Is shoe size continuous or discrete?

Discrete data is numerical data that can only take certain values. The number of people on a fair ground ride, the score on a pair of dice, or a shoe size are all examples of discrete data. Continuous data is numerical data that can take any value within a given range.

Is human skin color discontinuous 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.

IS fingerprint continuous or discontinuous 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.

Is shoe size discontinuous variation?

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

Is height continuous or discontinuous variation?

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. This shape of graph is typical of a feature with continuous variation.

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 age a discrete variable?

Is Age Discrete or Continuous? Technically speaking, age is a continuous variable because it can take on any value with any number of decimal places.

Is number of siblings discrete or continuous?

The number of siblings and student height represent numerical variables. Because the number of siblings is a count, it is discrete. Height varies continuously, so it is a continuous numerical variable.

Is hair color discrete or continuous?

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.

Is hours of TV discrete or continuous?

It depends how did you record the time, e.g. if you count days, or record hours rounded to the nearest hour then it is rather discrete; when you record days, hours and minutes of something happening, then it is closer to continuous.

Is temperature discrete or continuous?

Temperature is continuous variable as it does have fractional value too. For example: Today's temperature is 30. 5 degree Celsius, here 30. 5 is not a discrete variable and hence is a continuous variable.

Is time continuous or discrete?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person's age in years.
