Use a diploid cell that has 5 Types of chromosomes. Make a table and Count the number of unreplicated chromosomes, # replicated chromosomes, # DNA, policy (1N v 2N) in G1, G2, end of Mitosis and Meiosis I & II. 4. Draw the above cell and differentiate between the daughter cells produced after Mitosis, Meiosis I, Meiosis II divisions, in diagrams and in descriptions.
#unreplicated chromosomes | #replicated chromosomes | #DNA molecules | ploidy | |
G1 | 10 (10 chromatids) | 0 | 10 | 2n |
G2 | 0 | 10 (20 chromatids) | 20 | 2n |
End of mitosis | 10 (10 chromatids) | 0 | 10 | 2n |
End of meiosis 1 | 0 | 5 (10 chromatids) | 10 | n |
End of meiosis 2 | 5 (5 chromatids) | 0 | 5 | n |
Description -
10 unreplicated chromosomes are present in G1.
10 replicated chromosomes are present in G2 because DNA duplication has occured in S phase.
After mitosis, the cells will be diploid and 10 unreplicated chromosomes are present.
After meiosis one, the cells will be haploid and 5 replicated chromosomes are present.
After meiosis two, the cells will be haploid and 5 unreplicated chromosomes are present.
A chromosome having two sister chromatids is replicated.

2) A diploid cell has 8 chromosomes in G1 of interphase. Draw a picture of this cell with its chromosomes at the following stages. Indicate how many DNA molecules are present at each stage. (4 pts.) a. Metaphase of mitosis c. Metaphase I of meiosis b. Anaphase of mitosis d. Anaphase ll of meiosis
A somatic cell from a diploid species with 2n=4 (4 chromosomes or two sets of homologous chromosomes) is undergoing mitosis. Draw the cell and chromosomes during G1, during G2, during metaphase, and the two cells that result from mitosis at the end. Label each stage in your drawing, and also label sister chromatids and homologous chromosomes as appropriate.
A diploid somatic cell has 32 chromosomes total. At the end of mitosis, each daughter cell would have ______ chromosomes. At the end of meiosis I, each daughter cell would have ______ chromosomes. At the end of meiosis II, each daughter cell would have ______ chromosomes.
3. A diploid cell with eight chromosomes undergoes meiosis. (7 pt) a. How many chromosomes are there in each cell after meiosis I? How many daughter cells are made after meiosis I? Are the daughter cells diploid or haploid? (1.5 pt) How many chromosomes are there in each cell after meiosis ll? How many daughter cells are made after meiosis II? Are the daughter cells diploid or haploid? (1.5 pt) What two mechanisms allow genetic variation among the gametes produced...
A diploid eukaryote organism has 3 unique chromosomes. Chromosome is a metacentric chromosome, chromosome II is telocentric chromosome, and chromosome III is a submetacentric chromosome. How many total chromosomes do the somatic cells of this organism have in G1 of cell cycle? How many total chromosomes do the somatic cells of this organism have in G2 of cell cycle? How many total chromosomes are in a germ cell in the ovary of this organism that is in Anaphase of Meiosis...
Indicate whether the cells listed are haploid or diploid ? The parent cell in mitosis. The daughter cells in mitosis. The parent cell in meiosis. A cell that is in the G2 phase of the cell cycle. A cell that has finished meiosis I, but has not begun meiosis II.
SUMMARY – COMPARE MITOSIS AND MEIOSIS 1. What structures are present in the phases? How many? (Use numbers like 2n, 1n, etc., and terms like dyads, tetrads, replicated chromosomes, chromatids, chromosomes, ...)

1. Represent all chromosomes in a 2n = 4 cell before replication. Number the homologous chromosomes as you would in a karyotype (e.g., Chromosome 1, Chromosome 2). 2. Gene F is on Chromosome 1 and gene G is on Chromosome 2. This cell carries two different alleles of gene F (called F and f), and two different alleles of gene G (called G and g). Label these alleles on the unreplicated chromosomes that you drew above. 3. In the space...
