1) Compare and contrast mitosis and meiosis. Give at least 4 similarities and/or differences.
2) SEE FIRST IMAGE TO ANSWER
There are two processes in meiosis that contribute to genetic variation.
Name each process. (0.5 marks)
Identify the meiotic stage it occurs in, and identify that stage in the diagram above. (1 mark)
Explain how each event contributes to genetic variation. (1 mark)
3) SEE SECOND AD THRID IMAGE TO ANSWER
A) Type of Nondisjunction (Identify the meiotic stage.): _______________________
Daughter Cell 1 Daughter Cell 2 Daughter Cell 3 Daughter Cell 4
Number of Chromosomes in Each Daughter Cell
B) Type of Nondisjunction (Identify the meiotic stage.): _______________________
Daughter Cell 1 Daughter Cell 2 Daughter Cell 3 Daughter Cell 4
Number of Chromosomes in Each Daughter Cell
4) The conifer plant has 18 chromosomes. For each of the four stages on the diagram of the conifer life cycle, labelled A-D, identify whether the stage is haploid or diploid, and indicate the number of chromosomes that would be found in the cells at each stage.
5) Oogenesis is the process of female gamete (ovum or egg) production in animals. Spermatogenesis is the process of male gamete (sperm) production in animals. Although both processes produce gamete(s), there are distinct similarities and differences between the two.
Compare and contrast oogenesis to spermatogenesis by drawing a diagram showing the two processes. In your hand-drawn diagrams, be sure to include
when the processes of mitosis, meiosis I and meiosis II are occurring
identify each germ cell structure and its ploidy
highlight 4 differences between the two processes
