Trans­gen­er­a­tional im­pact

of ex­po­sure to pes­ti­cide methoxy­chlor stays for gen­er­a­tions and can cause dis­eases re­lated to the kid­ney and ovaries. Methoxy­chlor was in­tro­duced in 1948 as a safer al­ter­na­tive to DDT. How­ever, it is known to dis­rupt the en­docrine sys­tem. Sci­en­tists sus­pect that the trans­gen­er­a­tional im­pact of methoxy­chlor is due to its abil­ity to con­trol how genes are turned on and off, even though it does not have an im­pact on the DNA.
