A genetic counselor can also use the principles of population genetics in his advising. What is the basis for this type of counseling?

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.  

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
