Vedclass · Answer

(D) Variation in biological organisms,particularly during sexual reproduction,is primarily caused by the process of crossing over during meiosis.Crossing over involves the exchange of genetic material between non-sister chromatids of homologous chromosomes.This process leads to new combinations of genes,which results in genetic variation among offspring.Therefore,the correct answer is the exchange of genetic material.
