Dominant mutations with large, clear-cut manifestations can be expected to be much rarer than those with smaller, but possibly quite significant, effects on bodily dimensions, life span, etc. But the detection of these latter is a matter of great difficulty with present techniques.

Studies have proven that both survivors of the attacks and their children, who had been exposed to high radiation, are at risk of developing cancer. [4] A mutagen like radiation has the ability to increase the likelihood of a mutation-taking place in the body, which leads to cancer. [2]

When ionizing radiation causes DNA damage (mutations) in male or female reproductive (“germ”) cells, that damage can be transmitted to the next generation (F1). This is in contrast to mutations in somatic cells , which are not transmitted.

Genetic damage as a result of radiation exposure is generally believed to consist of the same elements found in so-called spontaneous mutations. This view may change as knowledge of the molecular mechanisms of heritable mutations in higher organisms develops.

Though geneticists knew that radiation caused heritable mutations in experimental organisms such as Drosophila, and believed it caused mutations in humans, the Neel-Schull findings were not a surprise.

Genetic studies in the offspring of atomic bomb survivors have been conducted since 1948 at the Atomic Bomb Casualty Commission and its successor, the Radiation Effects Research Foundation, in Hiroshima and Nagasaki.

This phase of the study recognized both the emergence of important new technologies for the study of these cohorts of children and the growing insights into the genetic contribution of mutation in the parental generation to congenital defect, malignancy, and early death.

The explosion of atom bombs over the cities of Hiroshima and Nagasaki in August 1945 resulted in very high casualties, both immediate and delayed but also left a large number of survivors who had been exposed to radiation, at levels that could be fairly precisely ascertained.
