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.
