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 below, represent the chromosomes of this cell after replication. Label all the alleles on the replicated chromosomes in your drawing.
4. Draw the chromosomes as they would appear in the cell during metaphase of mitosis. Label all alleles on all chromosomes. Be sure to include the mitotic spindle in your drawing.
5. Draw the chromosomes in the two daughter cells after mitosis and cytokinesis are complete. Label all alleles on all chromosomes.
6. Each daughter cell shown above is ______. diploid haploid

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.
Draw and label the phases of mitosis and the following structure
in an animal cell.
Word bank: Chromosomes, spindle, nuclear envelope,
cytokinesis
Draw and label the Phases of Mitosis and the following Structures in an Animal Cell Word Bank: Chromosomes, spindle, nuclear envelope, cytokinesis. Interphase Prophase Metaphase Anaphase 00- Daughter Cells Telophase
Simulate mitosis by drawing and include the following: Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 homologous pairs of chromosomes (the cell has more chromosome pairs, but we are just looking at 2 of them) It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . There should be one gene on each chromosome. Go through...

Chromosome duplication takes place. C. Chromatin becomes tightly coiled. D. The mitotic spindle forms. Question 3: The correct sequence of stages of mitosis is A. prophase, metaphase, anaphase, telophase B. telophase, prophase, interphase, anaphase, metaphase C. interphase, anaphase, prophase, metaphase, telophase B. metaphase, prophase, anaphase, telophase Question 4: Human cells contain 23 pairs of chromosomes A....
2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...
QUESTION 1 Match each of the following to the correct term. The "central body" responsible for maintaining and orienting the mitotic spindle. This "central body" replicates during S-phase. A structure within the "central body" that consists of two microtubule triplet structures. Condensed complex between DNA and proteins as it is observed in cells. The degree of condensation varies in different cells and throughout the cell cycle. This term is nearly synonymous with chromosome, with the exception that "chromosome" does...
Question 36 Homologous chromosomes pair along their length during prophase 1 of meiosis. While two homologues are paired, genetic exchange may occur between them in a process called _______ syngamy nondisjunction independent assortment crossing over Question 37 At the end of meiosis II, there are _______ 2 haploid daughter cells that are genetically different 4 haploid daughter cells that are genetically identical 4 haploid daughter cells that are genetically different 2 diploid daughter cells that are genetically identical 4 diploid daughter cells that are genetically differentQuestion 38 When do homologous chromosomes separate from...
A) Draw the cell on the right (note that the letters indicate
the gene and alleles present in each chromosome, show those letters
on every drawing) as it goes through the cell cycle and indicate
the main things that happen to its chromosomes at each stage
(label: sister chromatids, homologous chromosomes, G1, S, G2,
Prophase, metaphase, anaphase, telophase, cytokinesis, indicate the
3 checkpoints).
