WebA typical human cell probably expresses about 20% of its genes at any given time. Highly specialized cells, such as nerves or muscles, express only a tiny fraction of their genes. Although all the cells in an organism contain an identical genome, the subset of genes expressed in the cells of each type is unique. WebIn some cases, the answer is yes. Genes that are sufficiently close together on a chromosome will tend to "stick together," and the versions (alleles) of those genes that are together on a chromosome will tend to be inherited as a pair more often than not.
