Question

Quizplus · Accepted Answer

Short DNA repeats in a child's genome that don't match the size in either exposed parent indicate a mutation that occurred in the parent's germ cells due to radiation exposure. This type of mutation, called a de novo mutation, is not inherited from either parent and can be passed on to future generations.
