Linkage studies refer to tracing a particular trait within a family does this mean that twin and adoption studies are a type of linkage study?
No. Linkage studies use markers to identify chromosomal regions that may be linked to disease. Twin and adoption studies establish heritability and thus the genetic basis of a disease, not which chromosome or chromosomal region may be implicated. For this reason they are called genetic epidemiological studies.

What is a scientific model and how is it useful to scientists?
scientific model is a testable idea based on studies on a particular subject. It is useful to scientist for further studies and research on similar idea, subject.
What do you call someone who studies bears?
Firstly, koalas are not bears.There is no particular name for someone who studies koalas.People who study the field of animal Biology are zoologists. While there are specialised areas within this broad parameter (such as ornithologists, who study birds), there is no particular name for one who studies koalas. It is too narrow a field.
What are the two main types of data a scientist collect?
Data will be either qualitative (non numerical description) or quantative (numerical values assigned to a property). To give you an example, a meterologist may describe the sky on a particular day as cloudy (qualitative) with a 5 mile per hour wind (quantative). Studies can be classified as experimental studies or observational studies. The experimental study means that the scientist is able to treat or alter in some way the population. Medical studies of drugs frequently conduct experimental studies and collect experimental data. Observational studies, we collect data without altering the population. A good example is astronomical studies, where it is impossible to alter the population. Scientific studies need to be thorough investigations relying on good data and sufficient quantity of data in order to reach conclusions.

What is linkage disequilibrium?
Linkage disequilibrium is the non-random association of alleles at two or more loci. It is broken down by recombination. Linkage equilibrium = independence between allele frequencies at two different SNPs Linkage disequilibrium = Association between alleles at different SNPs (SNPs are Single Nucleotide Polymorphism - Pronounced snips)
What information does a linkage map provide?
A linkage map shows the relative positions of genes on a chromosome based on how frequently they are inherited together. It helps to understand the genetic distance between genes and their association with certain traits or phenotypes. Linkage maps are valuable tools for genetic studies, including identifying genes responsible for disease or traits of interest.
What is the key linkage group in the US?
I believe that the key linkage group in the United States is the "media". This assumption is based on scientific studies done at the university of Harvard law. It shows that when people watch television programs, they in turn soak material into their brains. This proves that the media is the key linkage group in the US. When people hear someone on TV say something, in turn they automatically believe everything that they hear.
What is a linkage map in genetic studies?
Linkage is a term which describes the tendency of certain loci or alleles to be inherited together. Genetic loci on the same chromosome are physically close to one another and tend to stay together during meiosis, and are thus genetically linked.
Why is mapping linkage data inefficient in humans?
Long life cycle, few progeny and the relatively few number of traits available to follow effectively and easily; not much real diversity. And many noticable traits are detrimental and often lethal; people are pretty complex.
Methods for determining the linkage group and genetic map in humans?
Linkage groups in humans are determined through genetic linkage analysis, which involves studying the inheritance patterns of specific genes or markers across families. Techniques like pedigree analysis and the use of single nucleotide polymorphisms (SNPs) allow researchers to identify co-segregation of traits, indicating proximity on chromosomes. Genetic mapping is further refined using genome-wide association studies (GWAS) to correlate specific genetic variants with traits or diseases, ultimately aiding in the construction of a genetic map. These methods collectively enhance our understanding of human genetics and disease susceptibility.
What is the linkage of settlement geography with other subjects?
Settlement geography is linked to various subjects like urban planning, sociology, economics, and environmental studies. It involves studying the distribution and organization of human settlements, which in turn affects urban development, social interactions, economic activities, and impacts on the natural environment. Understanding settlement patterns can provide insights into land use planning, resource management, social inequalities, and sustainable development practices.

Do Migraines effect blood clotting?
There have been studies proving a linkage between blood clots and migraines. The veins develop blood clots during the migraines. This can easily explain why migraine sufferers are more prone to having heart attacks and strokes more than the normal individual without migraines.

What are linked loci?
Linked loci refer to genetic loci that are physically close to each other on the same chromosome. These loci tend to be inherited together and exhibit genetic linkage, meaning they are less likely to undergo genetic recombination during meiosis. This phenomenon can impact inheritance patterns and genetic mapping studies.
