1. Answer- A. Sister chromatids of each chromosome are separated from each other ( Separation of sister chromatids occurred in Anaphase II of Meiosis II).
2. Answer- B. Telophase I The microtubules that make up the spindle network disappear, a new nuclear membranes and nucleolus developed. The chromosomes uncoil back into chromatin.
7. During meiosis II, Points: 1 @ sister, chrom sister chromatids of each chromosome are separated...

Match the following terms to the correct definition. 1. term used to describe the double stranded chromosomes present after DNA replication alleles A. cell division that results in the formation of B 4 cells each containing haploid number of chromosomes crossing over division of the cytoplasm type of cell division that results in the formation of 2 daughter cells genetically identical to parent cell pairing of homologous sister chromatids during prophase I...
alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
5. Which of the following is true about meiosis? A. Sister chromatids are pulled apart during anaphase I B. Sister chromatids are pulled apart during anaphase II 6. In which stage of prophase I do homologous chromosomes begin to pair (synapsis begins)? A. leptotema B. zygonema C. pachynema D. diplonema E. diakinesis 7. Which of the following is true about sex-determining chromosomes? A) They are independent during meiosis. B) They do not participate in meiosis. C) They act like homologous...
Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...
Identify the stages of meiosis by filling in the blanks, and then rearrange the sentences to place the stages in the correct order starting with prophase I. Drag the text blocks below into their correct order. anaphase II Sister chromatids separate and are pulled to opposite poles of the cell during www telophase II metaphase wwwwwww Nuclear envelopes reform around two separate haploid nuclei during prophase www Chromosomes line up in pairs along the plate during anaphase Nuclear envelopes reform...
Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...
Question 12 (2 points) Which of the following events of meiosis leads to the creation of haploid cells by the end of Telophase 1 of meiosis? 1) sister chromatids separate during Anaphase II 2) homologous chromosomes synapse and cross over during Prophase 3) homologous chromosomes separate during Anaphase 4) random fertilization 5) nondisjunction
Sister chromatids separate from each other during meiosis II only mitosis and meiosis I mitosis and meiosis II meiosis I only QUESTION 25 Which of the following occurs in meiosis but not in mitosis? chromosome replication alignment of chromosomes at the equator synapsis of chromosomes condensation of chromosomes
Experiment 3: Following Chromosomal DNA Movement through Meiosis In this experiment, you will follow the movement of the chromosomes through meiosis I and II to create gam- etes. Materials Procedure Trial 1 As prophase I begins, the replicated chromosomes coil and condense... 1. Build a pair of replicated, homologous chromosomes. 10 beads should be used to create each individual sister chromatid (20 beads per chromosome pair). The five-holed bead represents the centromere. To do this... For example, suppose you start...
7. What are chiasmata in a nucleus going through meiosis? a. they are sites where non-sister chromatids can exchange genetic material during meiosis. b. they are sites where sister chromatids can exchange genetic material during meiosis. c. they ensure that homologous chromosomes remain homologous after meiosis. d. they increase genetic variation among the products of mitosis. e. they prevent sister chromatids from separating. 8. A chromatid is: a. one of the pairs of homologous chromosomes. b. a homologous chromosome. c....
