Question

explain variations in detail for 5 mark question pls answer quick it's important ​

Answer 1

Answer:

Variation can be defined as the difference between the cells, organisms or group of organisms belonging to a particular species by environmental factors (phenotypic variation) or genetic differences (genotypic variations).

It is caused by gene mutations due to certain environmental factors and various combinations of genetic material.

Variation is important because it causes evolution and is the basis of heredity.

It is advantageous to a population as it enables few individuals to adapt to the environment changes thus, enabling the survival of the population...

What is Variation ?

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

Causes of Variation -

Major causes of variation include mutations, gene flow, and sexual reproduction. DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.

Types of Variation -

• Direct Variation, where one variable is a constant multiple of another.
• Inverse or Indirect Variation, where when one of the variables increases, the other one decreases (their product is constant)
• Joint Variation, where more than two variables are related directly.
