Genetic spontaneous mutations are produced by:Group of answer choicesunknown causes.x-rays.toxic chemicals.UV radiation.

Spontaneous genetic mutations can be caused by:

1. Unknown Causes: Sometimes, the exact cause of a mutation is not known. It could be due to errors in DNA replication or other unknown factors.

2. X-Rays: High-energy radiation such as X-rays can cause damage to the DNA, leading to mutations.

3. Toxic Chemicals: Certain chemicals can interact with DNA and cause mutations. These are known as mutagens.

4. UV Radiation: Ultraviolet (UV) radiation, like that from the sun, can cause damage to the DNA, leading to mutations.

So, all of the above options can produce genetic spontaneous mutations.
