health: Study Says Motion Sickness Is in the Genes


Study Says Motion Sickness Is in the Genes

If you feel an unpleasant queasiness while traveling in a car or boat, it could be genetic, according to a recent study by personal genomics company 23andMe. Using genetic data from more than 80,000 of its customers, 23andMe was able to link motion sickness to 35 genetic factors—many of which are involved in the nervous system, balance, and eye and ear development. However, having these gene variants does not guarantee that one will experience motion sickness. Research also showed that those who suffer from motion sickness are more likely to develop vertigo and migraines. More… Discuss

article: Genetic Counseling


Genetic Counseling

Genetic counseling is the process by which patients at risk of developing or transmitting an inherited disorder are advised of the nature and consequences of the disorder, the probability of developing it or passing it on, and the available treatment options. Typically, people seek counseling because they have a family history of genetic disorders or because their job or lifestyle exposes them to health risks like radiation or chemicals. What are some of the conditions commonly screened for? More… Discuss

NEWS: DNA TEST TO TELL IDENTICAL TWINS APART


 

 

DNA Test to Tell Identical Twins Apart

DNA analysis is an invaluable forensic tool, but it has its limitations. Until now, crimes and paternity cases involving monozygotic—”identical”—twins could not be resolved using DNA, since the genetic makeup of such twins is virtually indistinguishable given current analysis methods. Even though there are minute differences between the genetic codes of identical twins, time constraints and prohibitive costs have kept tests to detect them out of reach of law enforcement. However, a relatively quick and affordable new DNA test could be the answer investigators have been looking for. More… Discuss

GENETIC MUTATION SLOWS METABOLISM


Genetic Mutation Slows Metabolism

Obesity has long been viewed as a controllable condition that results from a combination of laziness and a lack of self-control. Although it is true that eating too much and exercising too little are factors in weight gain, scientific evidence is increasingly pointing to biological contributors as well. Researchers have found a genetic mutation that seems to increase appetite and slow metabolism. Many with this mutation are severely obese by early childhood. Previous research has uncovered several other genes that predispose people to obesityMore… Discuss

 

FOUNDER EFFECT (Hannibal Lecter)


Founder Effect

The founder effect is a form of genetic drift that occurs when a small group in a population splinters off and forms a new one. These founders can strongly affect the new colony’s genetic makeup far into the future, since their small gene pool may be unrepresentative of that of the population at large. Down the line, this can result in an increase in recessive traits, even maladaptive ones, like certain genetic diseases. What are some communities that have been impacted by the founder effect? More… Discuss
