Supplement. When a pair or set of genes are on the same chromosome, they are usually inherited together or as a single unit. For example, in fruit flies the genes for eye color and the genes for wing length are on the same chromosome, thus are inherited together.
This means that the individual shares much more of each parent's DNA than the 50% indicated by the table. Thus the table shows us that 50% of our DNA is directly received from each parent and not that the genes inherited from one parent are entirely different to those inherited from the other. What the table also shows us is that, beyond 7-degrees of relation, the number of genes shared in this manner is rather few.
