D) Genetic exchange between chromatids of replicated chromosomes

Question

Quizplus · Accepted Answer

- A) Random assortment of chromosomes along the equatorial plane contributes to genetic variation by shuffling the combination of chromosomes that go into each gamete.- B) Genetic exchange between chromatids of homologous chromosomes, also known as crossing over, increases genetic diversity by exchanging DNA segments between non-sister chromatids.- C) Crossing over is the process mentioned in B and directly contributes to genetic variation by allowing the exchange of genetic material between homologous chromosomes.
