But a burgeoning field known as epigenetics is showing that many cancers may not be caused by mutations in genes, but by chemical modifications that alter how the genes function. Such modifications to genes are epigenetic-literally on top of or related to changes in the DNA sequence.
There is plenty of evidence that demonstrates how epigenetic changes (and not changes in the DNA of a gene) have been passed on to the next generation. For example: 1  Drosophila melanogaster-the fruit fly has white eyes.2  Embryos develop in temperatures of 25 degrees Celsius.here are several epigenetic ways that a gene can be modified, that is having its expression altered without changes to its DNA. Two of the most widely studied are DNA methylation and histone modification. 1) DNA methylation-where methyl groups latch onto parts of a DNA sequence and can switch a gene on or off.
