Problem: How does sexual reproduction help to maintain genetic variation?
Select all that apply.
- Fertilization copies the DNA in an organism and creates a new organism with the same genetic code.
- Reduction division increases the number of chromosomes in a cell, giving the gamete more genetic material to pass on.
- Reduction division reduces the number of chromosomes in a reproductive cell, resulting in four daughter cells with different DNA.
- Fertilization, or the fusing of two gametes, creates an organism with a new combination of DNA.
