Variation. Variations are classified either as continuous, or quantitative (smoothly grading between two extremes, with the majority of individuals at the centre, as height in human populations); or as discontinuous, or qualitative (composed of well-defined classes, as blood groups in man).
Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces. Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Genetic variation is a result of subtle differences in our DNA.
Origin of variation between species Speciation is defined as the process by which, a group of organisms becomes isolated from original population, eventually resulting into the formation of new species.
A species is a group of related individuals that form a population that only breeds within that population. A variation is a deviation from the statistical norm. You will find variation within populations. Usually the variation follows a bell shaped curve, with outlying members being the …
What A Species Is
Variation. Variation is the differences between individuals within a species. This can be caused by inherited or environmental factors. Variation can be continuous or discontinuous.
If we move down to the species level, genetic diversity is how much genetic variation there is in a population. Genetic diversity is important because the more genes are in a population, the more likely that one of those genes will prove helpful in the face of threats such as climate change or a new disease.
