Problem solving is an integral part of doing science, yet it is challenging for students in many disciplines to learn. We explored student success in solving genetics problems in several genetics content areas using sets of three consecutive questions for each content area.

Simple Genetics Practice Problems

In Julya woman brought her husband to the hospital where our colleagues work in western Kenya. She reported that for several years he had been behaving abnormally, sleeping poorly, hearing voices that no one else could hear, and believing that people were talking about him and plotting to harm him. She was seeking help now because he was no longer able to work. The man was admitted to the inpatient Mental Health Unit and diagnosed with schizophrenia.

Her clothes and her hair were disheveled. She described people plotting against her and giving her dirty looks when she walked in the street, genetics problem solving.

She said she was having trouble sleeping. The clinicians looked at each other with apprehension: Might she have schizophrenia too? Ultimately, the daughter and four more members of the family were diagnosed with schizophrenia. While having six members of the same family diagnosed with schizophrenia is unusual, it has long been recognized that mental disorders can run in families.

And often members genetics problem solving such families differ in their symptoms. For reasons that we are just beginning to understand, one family member might be diagnosed with schizophrenia and another with bipolar disorder or depression. In Eldoret, genetics problem solving, Kenya, where this health facility is located, it is not unusual to have two or three relatives receiving care for mental illnesses, and this is likely to be the case in most settings globally.

The situation is no different in Boston and other cities in the United States. Much research has found that such family resemblance is influenced by genes more than by any other risk factor, and genes genetics problem solving emerging as important clues for new treatments. But research on the genetic basis of mental illness has so far largely excluded anyone who is not of European heritage.

That means that this Kenyan family, and other people of African descent, might not benefit from the new biological insights into mental illness. The finding that severe and chronic mental illnesses tend to cluster in families has spurred efforts to understand the genetic differences between people with these illnesses and those without.

By looking at DNA and untangling what is going awry in the brain to cause these mental disorders, we hope to spur the creation of new medications to treat these debilitating illnesses and reduce the suffering that comes with them. One of the main issues presented by this diversity problem is that any solutions including new medications are likely to work best for the people whose DNA the research was based on genetics problem solving people of European descent.

To help remedy this problem in psychiatric research, genetics problem solving, a team of researchers from the Harvard T. Chan School of Public Health, the Broad Institute of MIT and Harvard and several institutions in Africa are working together to study the genetics of schizophrenia and bipolar disorder.

NeuroGAP-Psychosis aims to do something that has never been done on this scale before: recruit 35, people in Ethiopia, genetics problem solving, Kenya, South Africa and Uganda to answer questions about their health, lifestyle and mental illness, and donate two teaspoons of saliva for DNA testing. With this data, we will be looking for important, genetics problem solving, clinically relevant genetic differences that might be found in people of African descent and may be less common in people of European descent.

In truth, genetics research cannot be done effectively in a narrow slice of humanity. Our hope is that the genetic data found in the NeuroGAP-Psychosis study, and in similar studies genetics problem solving in Mexico, China, Japan, Finland and many other countries, will be combined to help solve the mystery of the causes of schizophrenia and bipolar disorder.

Our greatest wish? To see better treatments reach all people suffering from severe mental illness, whether they are in western Kenya or in Boston.

Aug 13,  · Recent efforts to study the genetics of a number of illnesses have what many of us are calling a “diversity problem.” Most of the work in human genetics so far has focused on people of. Implementation of this problem using our generic algorithm for solving problems with genetic algorithms proceeded smoothly and intuitively. An advantage of our system made obvious by these tests is that changing parameters is as simple as changing static variables within the code.
