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

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.

∙ 12y agoI 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.

How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
What is stabilizing evolution?
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.
When individuals with an average form of a trait have the highest fitness?
Stabilizing selection
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
What is Stabilizing Selection and Distruptive selection?
A type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value.
What terms describes natural selection that acts against intermediate forms of a polygenic trait to increase genetic variation while not changing the average value of a trait within?
Disruptive selection
What is natural selection that acts against one type of extreme form of a polyygenic trait to reduce genetic variation and change the average value of a trait within a population called?
directional selection
What is the cause of stabilizing 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.
What is an emergenic 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.
What is a genetic trait?
A trait is an observable, physical characteristic of an organism (a phenotype). A FACTOR is the underlying genetic cause of the TRAIT (the genotype).
What are causes for mutations?
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.
What is a common cause of stablilizing 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.
What are the different ways in which individuals with a particular trait may increase in a population?
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.
What is the genetic composition determining a trait?
Genotype is the genetic makeup of a trait.
What does trait?
genetic likeness.
A genetic factor that covers up another genetic factor is called?
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
