Half of each person's DNA comes from their mother and the other half from their father. Back to Top.
Small Area Variations. Definition. Health Economics.

Blood groups are a good example: you are either one. blood group or another - you can't be in between. Such data is. called discrete (or categorical) data. Chi-squared statistical. calculations work well in this case. Discontinuous variation is controlled by alleles of a single gene or a small number of genes. The. environment has little effect on this type of variation. Continuous variation. In continuous variation there is a complete range of measurements from one. extreme to the other. Height is an example of continuous variation -. individuals can have a complete range of heights, for example, 1.6, 1.61, 1.62, 1.625 etc metres high.
