Answers
hey mate...
S.N.
Differences
Mitosis
Meiosis
1 Type of Reproduction Asexual Sexual
2 Genetically Similar Different
3 Crossing Over No, crossing over cannot occur. Yes, mixing of chromosomes can occur.
4 Number of Divisions One Two
5 Pairing of Homologs No Yes
6 Mother Cells Can be either haploid or diploid Always diploid
7 Number of Daughter Cells produced 2 diploid cells 4 haploid cells
8 Chromosome Number Remains the same. Reduced by half.
9 Chromosomes Pairing Does Not Occur Takes place during zygotene of prophase I and continue upto metaphase I.
10 Creates Makes everything other than sex cells. Sex cells only: female egg cells or male sperm cells.
11 Takes Place in Somatic Cells Germ Cells
12 Chiasmata Absent Observed during prophase I and metaphase I.
13 Spindle Fibres Disappear completely in telophase. Do not disappear completely in telophase I.
14 Nucleoli Reappear at telophase Do not reappear at telophase I.
15 Steps Prophase, Metaphase, Anaphase, Telophase. (Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I; (Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II.
16 Karyokinesis Occurs in Interphase. Occurs in Interphase I.
17 Cytokinesis Occurs in Telophase. Occurs in Telophase I and in
