Answer:The correct answer would be:
occurs in metaphase I - is random chromosome alignment resulting in variation.
occurs during sexual reproduction - fuses gametes to form offspring with genes from each parent
occurs in prophase I - exchanges genetic information between non-sister chromatids
Explanation: Metaphase I is a stage of meiosis I during which chromosomes are randomly aligned at the metaphase plate. The chromosomes are randomly distributed into two daughter cells after meiosis I. Random segregation of chromosomes adds genetic variation in a population.
Sexual reproduction involves the formation and fusion of gametes. Each gamete is contributed by each parent. The fusion of these gametes results in the formation of a new combination of genes which are different from either parent.
Prophase I is the first stage of meiosis I during which the event of crossing over takes place. Crossing refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes
