What percentage of patients with Sickle Cell Disease is not of African decent?
Sickle Cell Disease can be found in patients of any nationality or decent. Both parents must carry the recessive gene for this disease, and only then their offspring have a 25% chance of inheriting the disease. Those of African decent have approximately an 8% chance of inheriting the disease, Hispanics have about a 0.07% chance of inheriting the disease, and whites have roughly a 0.001% chance of inheriting the disease.
What is the probability of testing positive for the disease?
The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +P(you don't have the disease)*P(the test shows positive when testing someone without the disease).The second category is particularly important if the disease is rare but the probability of a type II error is large.
How does the knowledge of probability impact ones understanding of drug testing or tests for a particular disease?
The knowledge of probability impacts one's understanding of drug testing or tests for a particular disease because the test parameter could come out either as true or false, making the probability to be 1/2 for either scenario or status.
How is probability used in biology?
It's used commonly to estimate the traits of a child of two parents. For example, the probability of the child having blue eyes, or curly hair, or even having genetic disease.
What is frequency approach to probability?
The frequency approach or experimental probability involves the estimation of the probability of an outcome as the proportion of "successful" outcomes in repeated trials. I put "successful" in quotes because in epidemiology, a "successful" outcome is often a person catching a disease or infection and possibly dying as a result. I am not sure if anyone would consider that a success!
What is the probability of a baby inheriting a disease from parents?
For the case where the disease is a recessive trait (more likely), the probability is 1/2 that they will carry the diseased gene but not show it. If the disease is a dominant trait, the probability is 1/2 that they will get it and show it. Having said that, in the recessive case, if both parents are carriers, then there is a 1/4 case the child will get it from both and then show the disease. I have answered regarding genetically-transmitted diseases. Mental illness and other forms of "disease" will be different.

What is huntington's disease classified as?
It is a genetic disease. You can only "catch" it by inheriting the gene for it.
Does diencephalon cause huntington disease?
Huntington's is a genetically transmitted disease- you get it by inheriting the gene for it.
Is polycystic kidney disease more dominant in males or females?
It does not favor male or female, both have an equal chance of inheriting the disease. If a parent has the disease each child whether male or female have a 50% chance of inheriting the disease.
What is the probability of testing positive for the disease?
The probability isP(you have the disease)*P(the test shows positive when testing someone with the disease) +P(you don't have the disease)*P(the test shows positive when testing someone without the disease).The second category is particularly important if the disease is rare but the probability of a type II error is large.
What are the odds of inheriting a disease carried on a dominant allele?
high (scary voice) so beware
What is the probability that a girl will not have huntington disease?
50%
What is the probability that a randomly selected man between age 55 and 64 does not have this disease?
The answer will depend on what the disease is.
What is the probability that you will die of heart disease?
around 20-30%
Hurlington disease is an autosomal dominant disorder that affects the nervous system if a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks then?
In this situation, there is a 50% chance of inheriting the disease.
What is the only way you can get a genetic disease or sickness?
The only way one can get a genetic disease is by inheriting it through one's parents. Genetic diseases and sicknesses aren't contagious, except through birth.
