Is it possible to predict a child s IQ based on the number of normal cells present in the study?
In most cases chromosome studies are done using white blood cells. The number of blood cells containing 46 chromosomes may not accurately reflect the number of skin cells, heart cells, or brain cells with 46 chromosomes. Therefore, it is impossible to predict what affect, if any, the presence of these chromosomally normal cells will have on a child s development.
