Re: Exposed mice pass increased risk of leukemia to offspring

Their offspring were then injected with a second cancer-causing agent 
and monitored for the onset of leukemia and lymphoma. The mice injected 
with plutonium had DNA damage in their bone marrow and passed some of 
the damage on to cells in their offspring, increasing their 
vulnerability.

Since when has a change in the bone marrow passed on heritable traits to the somatic cells?  Sounds like somone has been studying Lamarckism.

Also, did the fathers of the British show elevated Plutonium levels or were they only occupationally exposed to elevated radiation levels.  Seems like two different pathways are described.
