Original Project
Reproduction, Genes, and Heredity
Genetic information in the form of DNA molecules is transferred from parents to offspring during reproduction.
Item RH051001: In asexually reproducing organisms, all of an offspring's DNA is identical to its parent's DNA.
In some kinds of organisms, reproduction occurs asexually (without the combining of two sex cells). How much of the DNA of the offspring is identical to the DNA of its parent in these types of organisms?
- All of the DNA
- None of the DNA
- Half of the DNA
- It varies from offspring to offspring.
- Distribution of Responses
- Students Responding Correctly
