A discrete trait is one which can only take a finite number of values (usually integer), such as how many members in your family. A non-integer set might be the answer to your age, in years, calculated to the nearest month.
A continuous trait is one which, IN PRINCIPLE, can take any value. In practice, the measuring instrument and recording will often result in the continuous trait being converted to a discrete one.

How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation. In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
Is IQ discrete or continuous?
IQ is generally considered a discrete variable because it is typically measured using standardized tests that yield specific score values, often in whole numbers. However, the underlying cognitive abilities that IQ tests aim to assess can be viewed as continuous traits, as they exist along a spectrum. Thus, while IQ scores are presented as discrete values, they reflect continuous underlying cognitive constructs.
Is the hair color of adults discrete or continuous?
The hair color of adults is considered a discrete characteristic because it can be categorized into distinct groups, such as blonde, brunette, red, and black. While there are variations and shades within these categories, the primary classification does not fall along a continuous spectrum like some physical traits. Therefore, hair color is best understood as a set of discrete options rather than a continuous range.
What are examples of discrete traits?
Discrete traits are characteristics that exhibit distinct categories or values, rather than a continuous range. Examples include flower color in pea plants (such as purple or white), the presence or absence of a particular trait (like the ability to roll one's tongue), and blood type (A, B, AB, or O). These traits are often determined by single genes or specific combinations of alleles.
What is dichotomous trait?
Dichotomous is a trait that separates completely a set of living organisms that belong to the same species. To put it simply an organism either has or it hasn't this trait. This is in contrast with continuous traits where there aren't any discrete categorizations. For example, blood type (A, B or O) are dichotomous traits whereas height, weight, life span and skin color are continuous traits.
Who determined that individual traits are determined by discrete factor' in what year?

What is the difference between where you got your looks from and who you got your looks from?
Looks are personal traits. You can't get personal traits from a location (where). You get them from your parents (who).
Who determined that individual traits are determined by discrete ''factors'' in what year?
20015
What are some examples of discrete traits?
Some examples of discrete traits include blood type (A, B, AB, O), fingerprints patterns (loop, whorl, arch), and tongue rolling ability (can roll tongue or cannot roll tongue). These traits have distinct categories or options with no intermediate forms.
ARE Human blood groups are an example of a trait that shows continuous variation.?
No, human blood groups are not an example of a trait that shows continuous variation. Instead, blood groups (such as A, B, AB, and O) are classified as discrete categories determined by specific alleles. Continuous variation typically refers to traits like height or skin color, which exhibit a range of phenotypes rather than distinct categories.
What is one difference between tracing the inheritance of autosomal traits and tracing the inheritance of sex-linked traits?
One key difference is that autosomal traits are located on the autosomes (non-sex chromosomes), while sex-linked traits are located on the sex chromosomes (X or Y). This difference affects how these traits are inherited and expressed, as sex-linked traits show different inheritance patterns among males and females.
When multiple genes determinethe phenotype of a trait What is this an example of?
When multiple genes determine the phenotype of a trait, this is an example of polygenic inheritance. In polygenic traits, the combined effects of several genes contribute to the expression of a phenotype, leading to continuous variation in characteristics, such as height or skin color. This contrasts with traits determined by a single gene, which typically exhibit discrete categories.
