Original Project
Reproduction, Genes, and Heredity
Genetic information in the form of DNA molecules is transferred from parents to offspring during reproduction.
Item RH007002: If a mutation occurs to a DNA molecule in an organism's skin cell before the organism reproduces, none of the organism's offspring will have the mutation.
A change commonly referred to as a mutation occurs to a DNA molecule in an organism's skin cell before the organism reproduces. When the organism reproduces, how many of its children will have the mutation?
- All of the organism's children will have the mutation.
- Some of the organism's children will have the mutation.
- None of the organism's children will have the mutation.
- It will depend on how much time passes between when the mutation occurs and when the organism has children.
