Discontinuous variation
Discontinuous variation refers to the occurrence of distinct, non-overlapping phenotypic traits in a population. This type of variation is usually controlled by a single gene or a small number of genes with major effects. In the case of goats having four horns instead of the typical two, this is an example of discontinuous variation.
Explanation:
Nature of variation:
- The occurrence of four horns instead of two in goats is a distinct and easily recognizable trait.
- This trait is not found in intermediate forms or as a continuum of variations. It is either present or absent.
Inheritance pattern:
- Discontinuous variations are often controlled by a single gene or a few genes with major effects.
- In the case of the four-horned trait in goats, it is likely controlled by a single gene or a small number of genes.
Heritability:
- Discontinuous variations are generally inherited and passed on from one generation to the next.
- If a goat with four horns reproduces, there is a high likelihood that its offspring will also have four horns.
Stability over time:
- Discontinuous variations tend to be stable and persist over time.
- The occurrence of four horns in goats is not a temporary or acquired variation. It is a stable and heritable trait.
Examples of discontinuous variation:
- Presence or absence of wings in insects.
- Blood types in humans (A, B, AB, O).
- Ability to roll the tongue.
Conclusion:
The occurrence of four horns instead of two in goats is an example of discontinuous variation. This trait is distinct, heritable, and controlled by one or a few genes. It is not a result of continuous or acquired variation.
