An X-ray technician has been careless about safety for years by not always wearing her lead apron. She gets pregnant and has a child with a severe genetic disorder. The genetic counselor tells the mother that the likely cause was her occupation. Which evidence best supports the counselor’s claim?(1 point) The long-term radiation exposure damaged bonds in DNA causing mutations in her egg cells, and led to an inheritable genetic disorder. The long-term radiation exposure damaged bonds in DNA causing mutations in her egg cells, and led to an inheritable genetic disorder. The stress of her job led to poor lifestyle choices, which caused the mutation leading to the inheritable genetic disorder. The stress of her job led to poor lifestyle choices, which caused the mutation leading to the inheritable genetic disorder. Changes to chromosomes and DNA sequences can occur during meiosis by mechanisms such as crossing-over, which caused the inheritable genetic disorder. Changes to chromosomes and DNA sequences can occur during meiosis by mechanisms such as crossing-over, which caused the inheritable genetic disorder. The long-term radiation exposure caused skin cancer, which led to the inheritable genetic disorder.

The penetration of radiation into the skin can lead to damage of the genetic materials. For the X-ray technician who was careless with safety, a piece of evidence that best supports the counselor’s claim is;

The long-term radiation exposure damaged bonds in DNA causing mutations in her egg cells, and led to an inheritable genetic disorder.

Given that radiations can cause mutations, in the human genetic material, it is advised that technicians wear lead aprons that will prevent the penetration of these rays.

If this is not done, the bonds in the DNA can be affected, leading to inheritable genetic disorders. Therefore, sentence 1 offers a fitting explanation.
