What is the differernce between family genetics and population genetics?

Population genetics deals with the genetics of large groups of individuals and the statistics/probability/inheritance patterns in those groups. On the whole
this field of study does not manipulate genetic material and is not directly involved in breeding studies.
One of the primary tenents of population genetics is that an allele will remain in
a population at the same frequency as long as it is neither selected for or against. (The Hardy-Wienburg Principle).

Family genetics deals with the analysis of genetics from a relatively small group of related individuals (and their ancestors) to evaluate the potential for inheritance of disease/defective alleles. Information from this type of study can be used by counselors who are discussing a family's concerns regarding reproduction and the immediate potential to produce a child with particular genetic disorders associated with the family or within a population subset with certain predisposition for genetic disorders...ex. sickle cell anemia, Tay Sachs,
et cetera.

How would genealogical data provide information for genetic researchers?
Genealogical information is information about families, who is related to whom and how. A genetics researcher needs to identify genetic traits. Having a large family already researched as to their relationships provides a genetics researcher with the basics of understanding the inheritance of traits within that family.
What is family friction?
Family friction is when there are problems in a family. The problems in a family could be between everyone or just between two people. But the problem between two people could cause tension in the whole family.
How are places connected?
This is quite an ambiguous question! If you are talking of family relations, there's genetics to think about. In a sperm and egg, each have a copy of chromosomes from the mother and father, when fused, the genes mix up in a unique way. The baby will have at least one characteristic of the biological parent. That always is a connection.If talking out of the scope, there is talk of molecularconnections, when genetic connections are not in the scope. This molecular connection is far wider than that of genetics, but it is hazy and not very well proven yet.Hope I've helped ))
How would you find a geneticist who would be interested in doing genetic mapping on your family for research and discovery purposes?
Several resources for locating a genetics professional in your community are available online at: http://ghr.nlm.nih.gov/info=consultation/show/finding_professional You could also buy a hot pocket.
How does genetic information pass unchanged from one generation to the next even when a specific trait is not exhibited?
This is a principle of population genetics based on the Hardy-Weinberg Principle. A trait that is neither selected for nor against will remain in the population at the same frequency. In most populations the frequency values can be back calculated from the percentage of the population that is homozygous recessive. The basic equations are p+q=1 and p (squared) + 2pq + q (squared)=1 The value of q (squared) is the frequency of homozygous recessive individuals in the population. So if 20% of the population is homozygous recessive, then q (squared) is .20. This makes q=.45 (approx.) So, in order to produce a population where 20% of all individuals are homozygous recessive a full 45% of all the alleles at that gene locus are recessive. p=.55 p+q=.55+.45=1.0 Now all the numbers for the homozygous dominant and heterozygotes can be calculated. The approximate percent of the population that is homozygous dominant is 30% with 50% of the population represented by heterozygotes. .3+.5+.2=1 As the gene frequency for an allele decreases the less likely two individuals that are heterozygous for the trait will be to breed and produce either a homozygous recessive individual or a homozygous dominant. In the case where a characteristic is dominant and has a low frequency, the trait will be seen in family lines but rarely has the opportunity to be passed beyond a small population because there is no selection for the characteristic. An example of this is 6 fingered (polydactyl) individuals, which is a dominant trait. They exist in the population but they are rarely seen.
Do you have a higher likelihood of breast cancer from your family genetics?
Yes, a person can have a high likelihood of breast cancer from the genetics of the family.
Which of these is an uncontrollable risk factors for disease apex?
genetics
Adam is the oldest child in his family there are six children in his family with billy being the youngest what percentage of their genes do they share?
The genetics of all of the children are random so in theory they could share between 1 and 99% of the genetics. Not 100% though because everyone is unique!

How does social study relate to population family for life drugs and aids?
What is the relationship between social studies, and population, family, drugs and Aids.
If a family member has Schizophrenia is it more likely that you will have Schizophrenia?
Statistically, yes. There is a strong correlation between schizophrenia and genetics. That said, schizophrenia occurs in about .5% of the general population. So while you are statistically more likely to develop symptoms than someone who has no schizophrenics in their family, it is still quite unlikely that you will develop symptoms.
Does dependency theory run in families genetics?
"The theory of dependency running in family genetics is an ongoing study. There is strong evidence that there is a genetic component to many dependencies therefore I would say that yes, it does run in family genetics."
I am 15 and 5'2 is that healthy?
it depends on the genetics of your family
What is the reason for stuttering in children?
Genetics is the reason in our family.
What has the author Carol Krause written?
Carol Krause has written: 'How healthy is your family tree?' -- subject(s): Genealogy, Medical genetics 'Between Myself And Them'
What jobs can you apply to after doing masters in human genetics?
this is a guess but maybe on thos websites that find family roots through genetics
When did modern study of genetics begin and with whom?
Throughout the Victorian era it was gradually realised that some diseases had a pattern of family inheritance, so it started in the 18th century. The structure of DNA was finally discovered in the 1950s, by Watson and Crick at Cambridge university.
