Crossing over is an important step in meiosis. Which best explains how crossing over increases genetic variation? (SC.912.L.16.17) * 1 point Crossing over results in offspring with DNA identical to both parents. Crossing over selects the most adaptive DNA from the parents' gametes. Crossing over creates new combinations of each parent's DNA in the gametes. Crossing over preserves the DNA of each parent to produce a genetically unique offspring.
1 answer
The correct answer is: Crossing over creates new combinations of each parent's DNA in the gametes.
This process increases genetic variation by allowing segments of DNA to be exchanged between homologous chromosomes during meiosis, resulting in gametes that contain a mix of genetic material from both parents. This recombination leads to offspring with unique genetic combinations.
