Hydrophilic
A phospholipid is comprised of a phosphate hydrophilic head, which means that it is "water-loving," and a fatty acid hydrophobic tail, which is "water-hating." The head and the tail are joined together by a glycerol molecule.
The phosphate head is attracted to water because it is charged (i.e. negatively). Water is a polar molecule, which means that there is an uneven distribution of charges within its molecular structure with the oxygen side being "more negative" than the rest of the atom (which is "more positive" near the hydrogen). Thus, the negatively-charged nature of the phosphate head and the parts of the water molecule which are positively charged enable the two to form an "attraction" towards one another.
On the other hand, the hydrophobic tail is nonpolar, which means that it does not have a "more positive" or "more negative" side or part in its molecular structure. These differences in structure with water make the hydrophobic tail unattracted to water molecules and more attracted to other uncharged, nonpolar molecules (such as fats and oils).

It is associated with more or less why a genetic counselor would need to look at distinct human populations, with which an individual is related to when doing certain kinds of tests. For instance, if someone knows about their ancestry then the counselor would be able to tell about the genetic disorders most commonly occurring in that particular ancestry.
The basic way of seeing at it from a population genetics point of view is how populations do differ genetically and how does it associate with the probabilities of exhibiting a mutation in the person.
