Question
What are the differences between members of the same species called?
- Predators
- Traits
- Selections
- Variations
Hint:
The trait difference can be continuous or discontinuous.
The correct answer is: Variations
Variation can be defined as the difference between individuals of same population. Even identical twins are not genetically identical. This is due to the difference in the genetic makeup of the two.
Causes of variation: genes or influence of environmental factors or combination of both.
Variations can be classified broadly into continuous and discontinuous variation.
In continuous variations, the trait under study does not have a specific range. For example, height or weight of an individual. The continuous variation is studied using bell-shaped curve and line of best fit explains the nature of trait. This type of variation is due to the influence of both genes and environmental factors.
In discontinuous variation, the trait under study will be limited to specific number or range as in case of blood groups or eye color. It is expressed in bar graph and the percentage of population having the trait can be studied. This type of variation is mostly under the influence of genes inherited from the parents.
- Difference between members of same species is called variation
- Variation can be due to influence of environment or inheritance of genes
- Variation can be continuous or discontinuous
