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
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.
1. The alignment of random chromosome takes place in metaphase that results in variation.
2. During sexual reproduction the fusion of male gamete and female gamete takes place. It is required for the formation of offspring that acquire genes from both the parent.
3. The non-sister chromatids exchange genetic information during prophase I.
Further explanation:
Metaphase I:
Metaphase I is the stage of the meiosis I. It is a process by which a single cell divides to form two daughter cells. During metaphase I, homologue pairs of chromosomes are lined up in the opposite direction or poles. The alignment of each pair is random and occurs at the center of the cell. This phase helps in ensuring that the equal number of chromosomes (two copies of chromosome) is present in the daughter cells.
Sexual reproduction:
Reproduction is the process by which a new living organism produces either from sexual or asexual method. Sexual reproduction is a biological process that requires male and female gamete. A female gamete called ova or egg has acquired half of the chromosome and a male gamete called sperm acquires another half of the chromosome. During fertilization, the male gamete fused with female gamete and forms a zygote. The zygote contains a complete pair of chromosome and it further developed into the embryo.
Prophase I:
Prophase is the part of the meiosis that only occurs in the eukaryotic cells because they contain genetic material (DNA). Prophase is the process that includes five different stages. In this phase, the allele (genetic material) crosses over and recombines that result in the formation of non-identical haploid chromatids.
