Question

What is the Meaning of Variation?

Answer 1

Organism change their body according to the changing environment.In genetics, variety refers to an individual who differs from others of his or her species in some way. A mutation in a gene that codes for a protein or RNA is the most common cause of genetic diversity. Individual characteristics are a product of both genetic and environmental variance.

Complete answer:
Everyone is a human being. They are both members of the same species. Your peers and friends may have varied eye and hair colours. There will be some boys and some girls. Some people will be tall, while others will be short.
Variation is the presence of differences between living organisms of the same species. Variation between different species is usually greater than the variation within a species. Any difference between cells, individual organisms, or groups of organisms of any species induced by genetic differences (genotypic variation) or the effect of environmental conditions on the manifestation of genetic potentials, as defined in biology (phenotypic variation). Physical appearance, metabolism, fertility, manner of reproduction, behaviour, learning, and mental ability.
Variances in the number or structure of chromosomes, as well as differences in the genes carried by the chromosomes, produce genotypic variants. Genomic variants include eye colour, body shape, and illness resistance. Polyploids are people who have multiple sets of chromosomes.Individual characteristics are a product of both genetic and environmental variance. For example, a dog's weight is determined in part by its genes (inherited) and in part by what it consumes (environmental).

Note:-
Variation refers to the differences in traits between individuals of the same species during reproduction, some variation is handed down from parents to offspring by genes. This is inherited variation. Differences in the environment or what an individual does cause some variety. Singing, learning, etc. do not get inherited from parents to offspring.
