An Investigation Into An Aspect Of Human Variation

Aim The aim of this investigation was to explore and analyse an aspect of human variation. Hypothesis There will be a positive correlation between an individual's foot length and their hand span. This may be due to linkage; the genes that create these characteristics may be positioned on the same chromosome so that they become linked, and are inherited together. This linkage causes the two characteristics to become associated so that a person with large …

… this investigation is sufficient to provide strong evidence to support the hypothesis 'there will be a positive correlation between an individuals foot length and hand span'. The anomalies in this investigation, although present, are not adequate to question the results and conclusions. However, in a future investigation an improvement on this accuracy through more precise measuring equipment and other improvements outlined above, might create even stronger correlation and greater evidence to support the hypothesis.
