Genes and Choromosomes

Genes play an important role in the basic makeup of cell structure that they also factor into our heredity. Everything from eye color to certain behavioral traits can be traced back to the genetic composition within the cells. This includes behaviors associated with autism. Researchers search chromosomes to find the defective genes.

When researchers suggest that a possible problem exists on chromosome 2, the problem would actually lie in a gene (or in genes) on that chromosome. Chromosomes are used to locate the genes in the cells. We can consider a chromosome to be a country and genes to be cities within that country.
