A change in the expression of a gene that is brought about by its translocation to a new site in the genome. For example, a previously active gene may become inactive if placed on a new site in the genome.
A phenotype that varies depending on the position of a gene or group of genes, in relation to other genes.
A term in genetics that explains how a gene’s expression is influenced, at least in part, by its proximity to neighboring genes. Ongoing electron microscope studies of genes within the chromosomes of a fertilized egg cell are gradually uncovering the traits that are likely to be inherited by the new baby.
