Human Somatic (non reproductive) cells have 46 chromosomes organized into 23 pairs. A human somatic cell goes into mitosis, how many chromosomes does each resultant daughter cell have?
A diploid species has four chromosomes per set for a total of eightchromosomes in its somatic cells. Draw such a cell as it wouldlook in late prophase of meiosis II and prophase of mitosis. Discuss how prophase of meiosis II and prophase of mitosis differfrom each other, and explain how the difference originates.
Mitosis and meiosis are both forms of cell division but have several fundamental differences. One of these is the difference between metaphase (in mitosis) and metaphase I (in meiosis). Describe how these two specific phases are different and how this difference changes the results of mitosis vs. meiosis.
Question 3: A woman suffers from albinism and is also a carrier for haemophilia. Draw a well- labelled diagram of a cell in Metaphase depicting the relevant chromosomes associated with these conditions. Identify the specific chromosomes (consult previous lectures) associated with these conditions. Your diagrams should clearly indicate the chromatids, chromosomes, genotypes, alleles, and cell structure needed in Metaphase. Use A/a to indicate alleles associated with albinism and H/h for haemophilia.
QUESTION 2 Which statement(s) about mitosis is/are true? Daughter cells produced by mitosis have cytoplasmic content (ie, organelles, cytoplasm, number of mitochondria, etc.) that is identical Chromosomes condense during cytokinesis Homologous chromosomes on separate kinetochores line up together at the metaphase plate Daughter cells obtain a copy of each chromatid from their parent cell During prophase, the mitotic spindle develops
A eukaryotic cell is diploid and contains 10 chromosomes (5 ineach set). In mitosis and meiosis, how many daughter cells will beproduced, and how many chromosomes will each one contain?
Which type(s) of cell division (mitosis, meiosis I,meiosis II) reduce(s) the chromosome number byhalf? Which type(s) of cell division can be classifiedas reductional? Which type(s) of cell division can beclassified as equational?

In mitosis, what chromatid combination(s) will be present during metaphase? What combination(s) will be present at each pole at the completion of anaphase?
Describe the similarities and differences between mitosis and meiosis. Discuss at least two similarities and two differences. (Be sure to include the specific information about both processes for each comparison -- for instance, if you identify something about number of chromosomes, be sure to identify that number for both processes, whether or not it’s the same.)
Mitosis DrawingIn this assignment you will track and draw the chromosomes of a diploid organism through all the stages of mitosis. Make sure to draw the alleles for genes A and B on the chromatids in every stage. For mitosis, remember that many events are going on in the cell that are relevant besides just the movement of chromosomes, so please fill in the cell with pertinent structures such as centrioles and spindles.
QUESTION 8 Which of the following events does not occur during mejosis I? O DNA exchange O crossing-over between homologous chromosomes O separation of sister chromatids O separation of homologous chromosomes O pairing of homologous chromosomes QUESTION 9 The sources of genetic variation during meiosis are: O crossing-over and the random assortment of maternal and paternal chromosomes. O random pairing of tetrads and random assortment of maternal and paternal chromosomes. O crossing-over and random pairing of tetrads. O random pairing of tetrads and mutations. O polyploidy and random pairing of tetrads.
