It is true that genes do not cause behavior, but genes create the conditions through their proteins that make some outcomes more likely than otners. Why do we behavior analysts persist in saying silly things, like genetics is unimportant. Question: if height is irrelevant in basketball, why do NBA basketball teams hire tall players? Answer because they can make more baskets on average and block more shots, than short players. Question: What makes them tall or short? answer: Molecular biologist Chao-Qiang Lai of the Jean Mayer U.S. Department of Agriculture Human Nutrition Research Center on Aging at Tufts University answers. This question can be rephrased as: How much variation (difference between individuals) in height is attributable to genetic effects and how much to nutritional effects? The short answer to this question is that about 60 to 80 percent of the difference in height between individuals is determined by genetic factors, whereas 20 to 40 percent can be attributed to environmental effects, mainly nutrition. So yes, short player can also be effective but less often. Do genes matter? Only if you want tall players who win more games. How likely is it that a white child from Norway will have sickle cell disease? The white child wont. How about a child from a Black couple? 1in 500. A Hispanic Family? 1 in 36,000. How about Tay Sachs disease? Approximately one in every 27 Jews in the United States is a carrier of the Tay-Sachs disease gene. For the general population, about one in 250 people are carriers, so the likelihood of two non-Jews having a child with Tay Sachs is very remote. Please tell me you are listening. Genes profoundly matter. Its looking increasingly like children with autism who make the greatest gains in ABA early intervention tend to have the type of autism that runs in families, rather than the more pervasive type with more severe disability, that appears to be less familial. Genes related to experience dependent synapse formation seem to be the factor. How does that diminish tne power of behavioral intervention? It doesnt.
