Solution for Quetsion 1
A. Chromosome number reduced from diploid to haploid.
meiosis I is previously called as reduction process, which reduce 2n (46 chromosome) cells to n (23 chromosomes)
solution for Question 2
A. During prophase I
crossing over is pairing of 2 homologous chromosomes and exchange their chromosome segments. It happens in prophase I stage of meiosis. Crossing over is occur in the Pachytene stage of prophase I and chiasmata (cross over) is seen in the diplotine stage (after pachytene).
All the best thankyou

Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...
Concept 13.2: Fertilization and meiosis alternate in sexual life cycles
Concept 13.2: Fertilization and meiosis alternate in sexual life cycles Chromosomes - karyotype - homologous chromosomes (homologs) - sex chromosomes vs. autosomes - haploid vs. diploid Life cycle (gametes/fertilization/zygote/adult) - meiosis Concept 13.3: Meiosis reduces the number of chromosome sets from diploid to haploid Meiosis 1 - Prophase 1 synapsis/crossing over
