If you were given a cell with 9 chromosome pairs, find the following: centromeres during mitosis prophase chromatids during meiosis metaphase I chromosome number during mitosis metaphase bivalents during pachytene chromosome number during meiosis telophase I
The dog Canis familiaris is a diploid organism with 39 pairs of homologous chromosomes. For the dog, how many chromosomes and chromatids are present in one nucleus at each of the following stages of the cell cycle? Also state whether each of the entries are diploid or haploid. i. One product of Telophase of mitosis ii. A meiocyte in Prophase I of meiosis iii. A meiocyte in Prophase II of meiosis iv. One product of telophase II of meiosis
A cell goes through meiosis in order to separate a set of replicated chromosomes into two haploid cells and then to separate these cells again without copying the DNA to form four haploid cells. The following diagram illustrates how chromosomes are divided up during the two splits in meiosis. For each split in meiosis, you will see three different representations of chromosome division. Select the answer option for each split that correctly shows the way meiosis divides the chromosomes. Which one shows the Second Meiosis Split?
Consider the true diploid plant cell (2n=2x=6) below wherein the light blue chromosomes A, B, C (from largest to smallest) are paternally derived. These chromosomes contain the same gene pattern and structural features as maternally-derived purple chromosomes A’, B’, and C’, respectively. Draw and label the chromosomes as observed in the following stages Anaphase (c.1), Anaphase I (c.2), and Anaphase II (c.3). Assume no crossing-over events occurred at Meiosis.
The garden pea (Pisum sativum) is normally a diploid and has 7 chromosomes in one set (in other words, n = 7). Use this information to answer the following questions: a. How many centromeres would be in a cell of a tetraploid pea plant? ______ b. How many total chromatids would be in a cell of a tetraploid pea plant in metaphase of mitosis? _______ c. How many total chromosomes would be in a cell of a pea plant that is monosomic for a single chromosome?
In a cell where 2n=20, nondisjunction of two pairs of chromosomes will results into what types of gametes? Identify the gametes by giving the equation and final chromosome number in the gamete.
As two students, who will be designated Student J and Student K, were studying together, they argued about the differences between Mitosis and Meiosis (both Meiosis I and Meiosis II). Student J maintained that it if they were looking at very good slides under the microscope and concentrated on Metaphase, it would be possible to tell the difference between the cells undergoing Mitosis, the cells undergoing Meiosis I, and the cells undergoing Meiosis II. Student K said it would be impossible to tell which nuclear division was occurring. Assume there are three unlabeled sets of very good slides of the cells of the common pea plant with one set showing Mitosis, one set showing Meiosis I, and one set showing Meiosis II. To repeat, the slides are unlabeled so the students don’t know which process is occurring in which set. However, the students know that the common pea plant has 14 total chromosomes (or 7 pairs of chromosomes). Explain carefully what Student J would be looking for at the…
Human cells normally have 46 chromosomes. For each of the following stages, state the number of chromosomes present in the particular cell.a) metaphase of mitosisb) metaphase I of meiosis c) telophase of mitosisd) telophase I of meiosis e) telophase II of meiosis (Remember that a pair of attached chromatids count as one chromosome.)
As shown gives the number of chromosomes in a haploid set of chromosomes. What is the lowest number in the table? What is the highest number? Most cells in plants are diploid, having two sets of chromosomes,so the number per nucleus should be doubled. How many chromosomes are present in each diploid potato nucleus? If a potato plant has 1 million cells, each with one diploid nucleus, how many chromosomes are present in the entire plant?
A diploid cell with three pairs of homologous chromosomes is shown on the left. Each letter represents an allele of a gene on each chromosome. A cell that is some version of the diploid cell is shown on the right. The dotted line in this diagram represents the metaphase plate. When more than one cell would be present as a result of mitosis or meiosis, only one representative cell is shown. In what phase are the chromosomes in the cell shown on the right?
