Question

What is this definition: 'Differences between organisms caused by differences in the DNA they inherit from their parents'?

  1. Species
  2. Genetic variation
  3. Environmental variation
  4. Crossing over

hintHint:

Difference that can be found even in identical twins.

The correct answer is: Genetic variation


    Even identical twins have different genetic sequence. This is due to the phenomenon of variation.
    Genetic variation is termed as the difference in genetic make up of two individuals of same species or population.
    Variation can be observed as difference in skin color, eye color, weight, height and many other physical traits.
    Variation can be discontinuous or continuous.
    Traits like eye color, blood group show limited range of variation and are called discontinuous variation. These variations are due to the genes inherited from the parents. This type of inheritable variation can be studied using pedigree chart.
    Some traits like height, weight show unlimited range of variation and are called continuous variation. These variations are due to the combined effects of environment and genes.

    • Even identical twins have difference in genetic makeup. This is due to genetic variation.
    • Variation causes difference in traits such as height, eye color, skin color and many more
    • Variation can be continuous or discontinuous
    • Variation is due to genes or due to combined influence of genes and environment
