Reproduction, Genes, and Heredity
Genetic information in the form of DNA molecules is transferred from parents to offspring during reproduction.
Item RH009002: A skin cell of an organism contains the same genetic information as the fertilized egg cell of that organism.
How does the genetic information in a fertilized egg cell (an egg cell that has combined with a sperm cell) compare with the genetic information in the skin cells of the adult organism that develops from the fertilized egg cell?
- The skin cells in the adult organism contain the same genetic information that was in the fertilized egg cell.
- The skin cells in the adult organism still contain some of the genetic information that was in the fertilized egg cell, but not very much of the information.
- Some of the skin cells in the adult organism contain all of the genetic information that was in the fertilized egg cell, but other skin cells contain just a little of the information.
- None of the skin cells in the adult organism contains any of the genetic information that was in the fertilized egg cell.
