Question
Comparing Mitosis and Meiosis Somatic cells of a mouse have 40 chromosomes. With regard to the mouse, fill in the following table with the appropriate numbers. Diploid Chromosome Number- 0 Haploid Chromosome Number-20 Mitosis Prophase Metaphase # of chromatids Per chromosome:- Anaphase Telophase Meiosis I: Prophase1 Metaphase # of chromatids Per chromosome, Anaphase' Telophase l Meiosis II: Prophase Metaphase II Anaphase II Telophase " # of chromatids Per chromosome: Write the total number of chromosomes and chromatids per cell (cytokinesis - after cytokinesis is complete G1 end of S G2 Chromosomes Chromatid Prophase Metaphase Anaphase Telophase After Cytokinesis Mitosis Chromosomes Chromatid Prophase I Metaphase IAnaphase I Telophase I After Cytokinesis Meiosis I: Chromosomes Chromatid e Il Metaphase IIAnaphase Il Telophase lIAfter Cytokinesis Meiosis liI: Chromosomes ChromatidExplanation / Answer
Mitosis:
Prophase Metaphase Anaphase Telophase
Number of chromatids per chromosome 2 2 1 1
Prophase: Chrmosome condense and each cromosome consists of pair of chromatids
Metaphase: Chromosomes aline on hypothetical mid plate.Bipolar attachmetn of chromosome to the spindle pole.
Anaphase: Sister chromatids separate and migrate towards opposite end of cell
Telophase: Chromosome decondense.
Meiosis I: Prophase I Metaphase I Anaphase I Telophase I
Chromatids per chromosomes 2 2 2 2
In metaphase I there is unipolar attachment (i.e sister chromatids attach to same spindle pole) and in anaphase I there is chromosome separation while in anaphase II there is sister chromatid separation and in meataphase II bipolar attachment(i.e sister chromatods attach to two different pole).

Chromosomes per cell 40 40 40
Chromatids per cell 40 80 80
G1:Proteins are synthesize which are required for DNA replication
S phase:DNA replication occur,each chromosome consists of two sister chromatids,here DNAamount is doubled but ploidy level is same.
G2 :Proteins are synnthesize which are required for mitosis, meoisis.
