OBJECTIVES

Relate the specific events occurring in each of the stages of the cell cycle. (ALD)

Describe the process of meiosis I and meiosis II and what is occurring specifically at each phase.

Explain crossing over and how it affects the phenotype in a species and contributes to genetic variation.

Describe the role of meiosis in sexual reproduction and how it contributes to genetic variation.

Compare and contrast homologous chromosomes and sister chromatids.

Differentiate between haploid and diploid cells.

Describe the role meiosis plays in the formation of haploid gametes or spores.

Identify the functions of cell division in unicellular and multicellular organisms, e.g. reproduction, repair, and growth.

Differentiate the process of meiosis and mitosis and/or show how these processes may contribute to or limit genetic variation. (ALD)

Describe the process of independent assortment (will be
Segway to Topic XIX) in the resulting cells in meiosis.

Explain how independent assortment during meiosis contributes to genetic variation.

Explain how mutations in gametes may result in phenotypic changes in offspring.

I am able to differentiate the processes of mitosis and meiosis and/or show how these processes may contribute to or limit genetic variation.
I am able to contrast the processes of mitosis and meiosis and specify if these processes may contribute to or limit genetic variation.
I am able to recognize that mitosis and meiosis are different processes that have different outcomes.
LEARNING PROGRESSION
I am able to differentiate the processes of mitosis and meiosis and describe how these processes may contribute to or limit genetic variation.
I am able to recall that reproduction can be asexual or sexual.
SAMPLE PROGRESS MONITORING AND ASSESSMENT
ACTIVITIES
Compare the level of genetic variation in a bacterial colony to the level of variation in an animal population. Defend an argument on how sexual reproduction increases the variability of a species and protects that species in terms of natural selection.
Make a cartoon or skit where the characters are cells going through mitosis and meiosis describing the processes of each with an emphasis on how, where, and when each process occurs.
Make a graphic organizer that emphasizes the differences between mitosis and meiosis in chromosome number, genetic variation, number of cells produced, and type of reproduction.
Make a Venn Diagram showing the similarities and differences between the final products of mitosis and meiosis and how those cells are used.
