Answer:
The mutations that were found in the parents were mostly somatic mutations
Explanation:
It has been mentioned in the question that leukemia was mainly found in the persons who were directly exposed to the radiation and it was absent in their children so this fact suggests that the mutations that were found in the parents were mostly somatic mutations and thus they are not transferred to the children from their parents. 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.

Tundra is used to describe types of vegetation in the treeless high latitudes between taiga and polar ice caps, and at high altitude across the mountain above timberline.
POSITIVE AND NEGATIVE INTERACTIONS:-
The tundra is perhaps the most fragile of all the biomes because of its short growing season. A willow 10 centimeter ( 4 inches) high may have a trunk 7 centimeter in diameter and may be 50 YEARS OLD.
