Consider a diploid cell that contains three pairs of chromosomes designated AA, BB, CC. each pair contains a maternal and a paternal member (eg. Am and AP, etc). Using these designations, answer the ff. questions: (You can draw your answers but label chromosomes) a. In mitosis, what chromatid combinations will be present during metaphase? What combinations will be present at each pole at the completion of anaphase? b. During meiosis I, draw all possible alignments of chromatids at metaphase. C. Assume that during meiosis I, nondisjunction of the C chromosomes occur. What types of gametes will they form and what is the chromosome number of the resultant gametes?

consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. Each pair contains a maternal and a paternal member (e.g., Am and Ap, etc.). Using these designations, demonstrate your understanding of mitosis and meiosis by drawing chromatid combinations as requested. Be sure to indicate when chromatids are paired as a result of replication and/or synapsis. You may wish to use a large piece of brown manila wrapping paper or a large cut-up paper bag and work with another student as you deal with these problems. Such cooperative learning may be a useful approach as you solve problems throughout the text. Draw all possible combinations of chromatids during anaphase II in meiosis.
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?
Are the other phases of mitosis equal (or close)? Suggest a reason for any differences in the timing of mitosis phases.
What is the correct chromosomal condition at prometaphase of mitosis? A B C D E
A diploid cell has 4C genetic material and 16 chromosomes at the start of cell division. Identify number of set/s of chromosomes per cell after mitosis, number of set/s of chromosomes at Telophase 1, and number of chromosomes per cell at Telophase 1.
illustrate and briefly describe the alignment, pairing, and disjunction ofsister chromatids during mitosis. Include the molecular complexes cohesin and shugoshin and the enzyme separase.
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.)
Determine whether the following figures portray either Mitosis or Meiosis and identify its specific stage of cell division. (e.g. Mitosis- Prophase)
A cell with the diploid number of 46 is divided by mitosis. Two daughter cells are formed, one with 45 chromosomes and one with 47chromosomes. During which phase of mitosis did the error occur that resulted in these abnormal chromosome numbers?
For below problem, consider a diploid cell that contains three pairs of chromosomes designated AA, BB, and CC. Each pair contains a maternal and a paternal member (e.g., Am and Ap). Using these designations, demonstrate your understanding of mitosis and meiosis by drawing chromatid combinations as requested. Be sure to indicate when chromatids are paired as a result of replication and/or synapsis. You may wish to use a large piece of brown manila wrapping paper or a cut-up paper grocery bag for this project and to work in partnership with another student. We recommend cooperative learning as an efficacious way to develop the skills you will need for solving the problems presented throughout this text. Question: Assume that each gamete resulting from Problem 29 fuses, in fertilization, with a normal haploid gamete. What combinations will result? What percentage of zygotes will be diploid, containing one paternal and one maternal member of each chromosome pair?
Mitotic nondisjunction can occur, particularly in tumor cells. Assume a single nondisjunction event involving the X chromosome occurs in a cell undergoing mitosis in a human female. First, consider the daughter cell with the smaller number of chromosomes: How many total chromosomes will this cell have? How many X chromosomes will this cell have? Next, consider the daughter cell with the larger number of chromosomes: How many total chromosomes will this cell have? How many X chromosomes will this cell have?
