Whether epigenetic changes caused by polybrominated diphenyl ethers (PBDEs) can be passed on from parents to offsprings or not. Introduction: Epigenetics is the study of the ways through which the DNA and associated proteins produce altered gene expression due to their chemical modification. The chemical modification does not involve a change in the nucleotide sequence of the DNA. PBDEs are flame retardants which are found in a large number of household products. These are known to cause epigenetic changes in humans.

These are known to cause epigenetic changes in humans.

Expert Solution & Answer

Explanation of Solution

The epigenetic changes caused by PBDEs are heritable and can be passed from the parents to their children. In some research studies, PBDEs are found to cross the placenta and umbilical cord to the fetus, which can produce developmental disorders in the children. Chemical modification of the DNA is caused by DNA methylation which may cause an altered expression of certain genes. It leads to the epigenetic changes in the individual, which can be passed from parents to the offspring in the form of gametic alterations.

Hence, in case of the embryo, the epigenetic changes caused by PBDEs are transmitted through the placenta and umbilical cord.
