Remember, the pedigree describes the ancestry of our family. So basically, if we look at individual one and individual two, what this line describes is the fact that this is a married couple and they have three children, five, six and seven, which are all normal with respect to the phenotype. Now, this is couple number two. So we have three and four, basically mates. They produce child eight and child nine. So this is our mother that has a normal phenotype.
