DNA in Sperm and Ovum
When sperm and ovum unite during fertilization, they each contribute their unique DNA to form a new organism.
Separate Existence of DNA
- Sperm and ovum each contain half the genetic material required for a complete organism.
- The sperm has 23 chromosomes, and the ovum also has 23 chromosomes, totaling 46 in the fertilized egg.
Merger of DNA
- Upon fertilization, the nuclei of the sperm and ovum merge.
- This fusion creates a zygote with a complete set of chromosomes (46 in humans), combining genetic information from both parents.
Genetic Variation
- The unique combination of DNA from both the sperm and ovum results in genetic variation.
- Each offspring inherits traits from both parents, leading to diversity in characteristics.
Subsequent Generations
- The zygote develops into an embryo and eventually into a new organism.
- During meiosis, which occurs in the sex cells, the DNA is shuffled and randomly assorted, ensuring that each gamete (sperm or ovum) carries a unique set of genetic information.
Conclusion
- After fertilization, the separate DNA from sperm and ovum merges to form a complete set of DNA.
- This process ensures that the new organism has a unique genetic profile, differing from its parents and siblings.
