Question: Which of the following is the first phase of karyokinesis?
A Prophase
B Metaphase
C Anaphase
D Telophase
Answer: Prophase
| Aspect | Mitosis | Meiosis |
| Introduction | · Mitosis produces two genetically identical daughter cells for growth, repair and asexual reproduction. | · Meiosis produces four genetically diverse daughter cells for sexual reproduction and genetic diversity. |
| No. of divisions | · One division | · Two divisions (Meiosis I and Meiosis II) |
| Phases of karyokinesis
|
· Prophase
· Metaphase · Anaphase · Telophase
|
· Prophase I · Metaphase I · Anaphase I · Telophase I · Prophase II · Metaphase II · Anaphase II · Telophase II |
| Chromosome Number | · Maintained (Diploid ) | · Reduced by half (Haploid) |
| Genetic Diversity | · Limited genetic diversity among daughter cells. | · Significantly increased genetic diversity among daughter cells. |
| Homologous Chromosomes | · Do not separate in Anaphase | · Separate in Anaphase I |
| Sister Chromatids | · Separate in Anaphase | · Separate in Anaphase II |
| Significance | · Two genetically identical diploid daughter cells are produced. | · Four genetically diverse haploid daughter cells are produced. |
