Concept explainers
DRAW IT The diagram shows a cell in meiosis.
(a) Label the appropriate structures with these terms: chromosome (label as duplicated or unduplicated), centromere, kinetochore, sister chromatids, nonsister chromatids, homologous pair (use a bracket when labeling), homolog (label each one), chiasma, sister chromatid cohesion, and gene loci, labeling the alleles of the F and H genes.
(b) Describe the makeup of a haploid set and a diploid set.
(c) Identify the stage of meiosis shown.

- A cell has a diploid number of 6 (2n = 6). a. Draw the cell in metaphase of meiosis I. b. Draw the cell in metaphase of mitosis. c. How many chromosomes are present in a daughter cell after meiosis I? d. How many chromatids are present in a daughter cell after meiosis II? e. How many chromosomes are present in a daughter cell after mitosis? f. How many pairs of homologous chromosomes are visible in the cell in metaphase of meiosis I?arrow_forwardFigure 10.6 Which of the following is the correct order of events in mitosis? Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the mitotic spindle. The nucleus reforms and the cell divides. Cohesin proteins break down and the sister chromatids separate. The kinetochore becomes attached to the mitotic spindle. Cohesin proteins break down and the sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus reforms and the cell divides. The kinetochore becomes attached to the cohesin proteins. Sister chromatids line up at the metaphase plate. The kinetochore breaks down and the sister chromatids separate. The nucleus reforms and the cell divides. The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. Cohesin proteins break down and the sister chromatids separate. The nucleus reforms and the cell divides.arrow_forwardImagine a precursor germ cell (which will become a sperm or egg cell) from a diploid organism. Before the cell undergoes meiosis, it has a total of 40 chromosomes. Which of the following are true for this cell? Select all that apply The value of n is 40 After the first meiotic division, the cells will be haploid After the second meiotic division, there will be four cells When meiosis is complete, the sperm/egg will have 20 chromosomesarrow_forward

Draw and label two cells that illustrate the cell pictured below in Metaphase of Mitosis and Metaphase I of Meiosis. Indicate the position of all chromosomes, centrosomes and microtubules.arrow_forward
- cell type: 9) Label the figure below. Chromosome number: cytokinesis by: division type: А- В- С- D- E- the halves the number of chromosomes, and at the same time, stage. The result is 10) daughter cells event that causes genetic diversity takes place in called (n? 2n?). An organism with two of each kind of chromosome is said to be: (3) tetraploid (1) haploid (2) diploid (4) polyploid. In multicellular organisms, mitosis results in: (1) reproduction (2) growth and repair (3) sperm and egg production (4) fertilization. If an organism produced an egg that had 20 chromosomes, the body cells of that organism should have: (1) 10 chromosomes (2) 20 chromosomes (3) 30 chromosomes (4) 40 chromosomes. 11) is what helps us grow and is why we are all unique! Human female karyotype contains .... (number) pairs autosomal and sex chromosomes. separate to go opposite poles in Anaphase in mitosis, while in Meiosis in AnaphaseI.

Cytokinesis produces four unique daughter cells, spindle dissolve, and the nuclear envelope reappears. Spindle fibers pull homologous pairs of chromosomes apart. Nuclear envelopes of daughter cells dissolve, and chromosomes condense. Spindle fibers pull sister chromatids apart. Homologous pairs of chromosomes line up at the center of the cell in tetrads. Cytokinesis produces two daughter cells, spindle dissolves, and nuclear envelope reappears. Nuclear envelope dissolves, DNA condenses and crossing over occurs.
