Question

Which of the following statements is true?

  1. Continuous variation produces many different characteristics within a population.
  2. Discontinuous variation is due to genetically inherited characteristics.
  3. Continuous variations do not produce any characters.
  4. Discontinuous variations are not inherited traits.

hintHint:

Eye color is not influenced by environmental factors.

The correct answer is: Discontinuous variation is due to genetically inherited characteristics.


    Variation refers to the difference that exists between two individuals of the same species. The variation can be continuous or discontinuous.
    Skin color, height, weight are all common examples of continuous variation. The phenotypic variation can be unlimited. The variation does not entirely depend on genetic factors alone. Environmental conditions also play a role in determining the phenotypic trait of the individual.
    Blood group and eye color are common examples of discontinuous traits. These traits have limited number of variations. The genetic factor alone determines this type of variation. Based upon the genetic make up of the parent, the genes inherited by the offspring can be determined using a pedigree chart.

    • Variation is the difference in genetic makeup of two individuals of the same population
    • Variation can be continuous or discontinuous
    • Continuous variation is influenced by genetic and environmental factors
    • Discontinuous variation is influenced by genetic factors
    • Inheritance of genes from parents can be studied using pedigree chart
