Blood samples were collected from 19,000 children of people who were within 2000 meters of the atomic blast in Nagasaki, Japan.

Amino acid substitutions were investigated in 28 proteins and any variants detected led to an analysis of the child's parents' blood proteins to determine if the variant was an inherited or new mutation. Of the 289,868 genes examined, only one mutation was found in the children of parents exposed to the blast. None were found in the control group. This surprised the researchers, as animal studies clearly show that radiation causes mutations. In addition, the exposed parents did exhibit an increased incidence of leukemia and other types of cancers relative to unexposed people. These data suggest that _____.

As these mutations were induced due to exposure of radiation so it was induced mutation. And such induced mutations do not get inherited to the offspring.

How can you tell what genes are recessive or dominant when looking at actual gene setups?
devlian [24]
By looking at a gene set up or a punnet square,a gene that's dominant would be represented by a capital letter and recessive traits are represented by lowercase letters for example brown eyes are considered a dominant trait which can be represented as BB for homozygous, and Bb for heterozygous. Since blue eyes are recessive they would be bb.
