>> if a fefetus, a normal, genetically chromosomally normal fetus is exposed to a tiny bit of plutonium that lodges in its brain, veveloping brain, it can kill the cell that's gonna form the right half of the brain or the left arm. that's called teratogenesis, damage of a normal fetus, and that's what ththat drug thalidomide did when women took it for morning sickness and their babies were born with no arms or no legs. it does that. it also--plutonium in particular, which is highly mutagenic--lodges in the testicles. so it has a predilection for testicles, and i it lodgdges next to the spermatogonia, the cells that form the sperm, the precursors, and d it's an alpha emitter, highly mumutagenic. so it can mutate genes in thehe spe to induce genetic mutations and genetic disease down the generations. now, there are two sorts of mutations, dominant-- so if you have a baby with a dominant mutation like brown eyes, the baby will have brown eyes, or dwarfism-- achondroplastic dwarfism is dominant--but most mutations are recessive like blue eyes. you have to have two genes to have blue eyes. b
