How does radiation can cause genetic defects? Has this ever been observed in laboratory animals or humans?

Solution

Radiations can cause genetic defects due to mutations. Both the ionizing and non-ionizing radiations are mutagenic i.e., they are known to cause mutations. Alpha particles, beta particles, gamma rays, and X-rays are examples of mutagenic ionizing radiations and UV rays are non-ionizing mutagenic radiations. Ionizing radiations were the first radiations to cause mutations in multicellular organisms.

Muller used X-rays to mutate fruit fly, Drosophila for his genetics experiments.
