Continuous variation is the type of genetic variation showing an unbroken range of phenotypes in a population. Generally, measurable characters such as height, weight, and skin color are classic examples of continuous genetic variation. Moreover, the main feature of phenotype-wise continuous variation is the presence of intermediate phenotypes. The...
Discontinuous variation is the second type of genetic variation, showing two or more distinct phenotypes for a particular character in a population. Generally, it is the most simpletype of genetic variation to analyze. Basically, one gene determining a particular character usually has two alleles whose dominant forms exhibit one phenotype while the...
Continuous and discontinuous variation are two types of genetic variation seen among individuals of populations.Both occur due to the differences in DNA in different genomes caused by mutations and genetic recombination.Moreover, both cause phenotypic variation in different aspects including physical appearance, metabolism, fertility,mode of reproduction, behavior, learning and mental ability, and other obvious or...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.
Significance of Phenotypes
Phenotypes of continuous variation have a continuous range, and they are difficult to classify into specific categories. In contrast, phenotypes of discontinuous variation have a discontinuous range, and they can be categorized easily.
Intermediate Groupings
Intermediate groupings occur in continuous variation while no intermediate groupings occur in discontinuous variation.
Revision notes on 17.1.2 Variation: Discontinuous & Continuous for the CIE A Level Biology syllabus, written by the Biology experts at Save My Exams.
Variation refers to the differences in characteristics between individuals within a single species. There are two types of variation that we can observe: Continuous variation. Discontinuous variation.
Some features have discontinuous variation (limited variations falling into particular categories). Some features have continuous variation (can take any value within a range). Examples of features in humans, other animals and plants that show discontinuous and continuous variation.
