Reproduction, Genes, and Heredity
Genetic information in the form of DNA molecules is transferred from parents to offspring during reproduction.
Item RH049001: Sea anemones can reproduce asexually, and when they do, all of the offspring's DNA is the same as the DNA in its one parent.
In sea anemones (simple animals that live in the ocean), reproduction can occur asexually (without the combining of two sex cells). One or more offspring split off from the parent in a process called “budding.” How much of the offspring’s DNA is the same as its parent’s DNA in this type of reproduction?
- All of the offspring’s DNA is the same as the DNA in its one parent.
- Half of the offspring’s DNA is the same as the DNA in its one parent.
- None of the offspring’s DNA is the same as the DNA in its one parent.
- Two-thirds of the offspring’s DNA is the same as the DNA in its one parent.
