Ask Your Question Jerome J. Schultz, neuropsychologist Eileen Marzola, special education teacher A growing body of research suggests that chemicals released into the environment may at least partially explain the alarming increase in birth and developmental defects now seen in American children.

Extractions: This assignment is worth 25% of your homework grade. Parts A and B are due Thursday, April 23, 1998, 11:59pm . Part C is due Tuesday, April 28, 1998, 1:00pm . On Friday, April 24, the code for parts A and B will be made available to you so you can use it for part C even if you didn't complete Parts A and B yourself. In this assignment, you will write a simple genetic algorithm (GA) and apply it to the problem of evolving strategies for playing Iterated Prisoner's Dilemma (IPD). The code to play the game and test strategies against one another is already implemented for you. What you need to do is write the code for the GA, apply it to the IPD problem, and analyze the results that you get. For our problem, there will be no distinction between genomes (chromosomes) and phenomes (individuals). In our GA we will represent each genome as a list of 1s and 0s and a population as a list of genomes. There are two parameters which we will treat as global variables: *crossover-rate* : the probability that crossover is applied to two selected parents. Set this to .7 initially.

Extractions: What Research is Being Done? Within the Federal Government, the leading supporter of research on TS and other neurological disorders is the National Institute of Neurological Disorders and Stroke (NINDS). The NINDS, a part of the National Institutes of Health (NIH), is responsible for supporting and conducting research on the brain and central nervous system. NINDS sponsors research on TS both in its laboratories at the NIH and through grants to major medical institutions across the country. The National Institute of Mental Health,the National Center for Research Resources, the National Institute of Child Health and Human Development, the National Institute on Drug Abuse, and the National Institute on Deafness and Other Communication Disorders also support research of relevance to TS.
Extractions: Quote of the Week Just as archaeological artifacts and style can be used to argue the opposite sides of diffusion vs. independent invention debates, so too can multivariate analyses of ancient human teeth and bones be used to support differing interpretations of modern maps of genes. Often the conflicting interpretations appear equally convincing. We must learn that the reading of gene frequencies may not be any more precise or straightforward than the archaeological interpretation of split-base bone points or Linearband pots or the physical anthropological diagnosis of metric and nonmetric traits from human burials Lawrence G.

Extractions: stabilizing selection Back to Last Page Full Glossary Definition: The natural selection strategy by which deleterious mutations are selectively removed from a population because they decrease the fitness of individuals who posess them. Stabilizing selection results in an overall decrease in genetic diversity. Examples: Pheylketonuria, a genetic disorder that inhibits the proper processing of dietary protien and, without proper dietary control, causes brain damage is an example of a deleterious genetic variation that is subject to stabilizing selection.
