pros- can clarify diagnosis's, find diseases, can get rid of a disease, prenatal testings, find out your future, and its all confidential cons- can have labratory errors, expensive, emotional, most insurance doesnt cover the costs, can have implications on the family, could potentially be used to create a bigger divide between the upper and working classes by form of modern eugenics
1- Let parents know whether their child has a genetic disorder.
2- Let parents change their life style to increase the child's life span.
3- Clarify your cancer risk.
4- Explains why you or other family members have developed cancer.
5- If you have a genetic abnormality that you don't want to pass on to children, getting tested (both you and your partner) will let you make informed decisions.
Only the genetic traits a person wants passed along will be passed to the next generation, hence the selective breeding of purebred dogs. Unfortunately, there is a higher probability in gene mutations.
I will use an example, cystic fibrosis. Firstly the gene responsible for the development of cystic fibrosis is identified, by DNA sequencing. The complementay section of DNA to this mutated gene is extracted. It is made radioactive and placed in the polymerase chain reaction to increase the quantity of the probes. Then these probes are mixed with a sample of single stranded DNA provided by the patient, if the patient does have cystic fibrosis then this probe will bind via complementary base pairing to the DNA of the patient. An X-ray film is then used, if the probe has binded with the patient's DNA, then the film will be exposed.
One of the advanages of genetic research is so we can find cures for diseases that can kill you like Down syndrome.
These tests that look into the essence of humanity, will allow scientist and physicians the opportunity and ability to alter the human genotype for better or worse.

Advantage: It can help save bears <3
Disadvantage: It harms mahogany
Genetic screening is the process of analyzing DNA samples to detect the presence of a gene or genes associated with an inherited disorder.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Without genetic diversity, natural selection cannot occur
A mechanism (most common) of natural selection where overall genetic diversity decreases due to particular trait or genotype getting 'fixed' into the population. It is usually represented as a parabola on a graph.
Stabilizing selection
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
Disruptive selection
directional selection
The type of selection that removes the fringe from both ends of phenotype distribution and establishing a means or average. Genetic diversity decreases and there is a stabilization on a particular trait.
An emergenic trait is a complex trait that arises from interactions between multiple genes and environmental factors. These traits are not simply inherited from a single gene but emerge from the interplay of various genetic and environmental influences. Examples of emergenic traits include behaviors, intelligence, and susceptibility to certain diseases.
A trait is an observable, physical characteristic of an organism (a phenotype). A FACTOR is the underlying genetic cause of the TRAIT (the genotype).
Differences in the genetic code that lead to advantages above other members of the species. Thus if it is a valued trait it will be passed on.
The type of selection that removes the fringe from both ends of phenotype distribution and establishing a means or average. Genetic diversity decreases and there is a stabilization on a particular trait.
Individuals with a particular trait may increase in a population through natural selection, genetic drift, gene flow, and mutations. Natural selection favors individuals with advantageous traits, genetic drift leads to random changes in allele frequencies, gene flow introduces new alleles into the population, and mutations create new genetic variation.
Genotype is the genetic makeup of a trait.
genetic likeness.
A dominant trait is a genetic factor that blocks another genetic factor. A recessive trait is a genetic factor that is blocked by the presence of a dominant fact
