This is a series of lesson activities for a unit on the topic of Meiosis for introductory biology students. The learning goals been correlated to the performance indicators of the NY Living Environment core curriculum, Next Generation Science Standards and the Common Core Learning Standards. While this lesson is designed for the New York State curriculum, it is very appropriate for other biology programs as well.
All pdf files are also available in editable word format to allow you to make changes to these files to best suit your course and your students.

Meiosis Learning Goals
Upon completion of this unit the student will be able to:
1. define the term gametogenesis.
2. recognize that chromosomes exist in pairs in body cells.
3. recognize that each species has a characteristic number of chromosomes.
4. define the following terms correctly; homologous chromosomes, diploid number, haploid (monoploid) number, gametes, and gonads.
5. explain how the chromosome numbers are halved in cells produced by meiosis.
6. recognize that meiosis only occurs in animals in gamete producing cells of the gonads.
7. explain how the species diploid number is maintained through meiosis and fertilization.
8. describe the first meiotic division and explain the following terms; tetrad and crossing over.
9. briefly describe the second meiotic division.
10. explain why cells formed as the result of meiosis show variation from each other and their parent cell.
11. correctly define the terms disjunction and nondisjunction.
12. explain how nondisjunction may result in Down's Syndrome or polyploidy.
13. compare and contrast the processes of spermatogenesis and oogenesis.
Students who demonstrate understanding can:
HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
Common Core State Standards Connections:
RST.11-12.1 Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account.
RST.11-12.9 Synthesize information from a range of sources (e.g., texts, experiments, simulations) into a coherent understanding of a process, phenomenon, or concept, resolving conflicting information when possible.
WHST.9-12.1 Write arguments focused on discipline-specific content.
MP.2 Reason abstractly and quantitatively.
NY Living Environment Core Curriculum Performance Indicators and Major Understandings
Performance Indicator 3.1
Explain the mechanisms and patterns of evolution.
3.1b New inheritable characteristics can result from new combinations of existing genes or from mutations of genes in reproductive cells.
3.1c Mutation and the sorting and recombining of genes during meiosis and fertilization result in a great variety of possible gene combinations.
Performance Indicator 4.1
Explain how organisms, including humans, reproduce their own kind.
4.1a Reproduction and development are necessary for the continuation of any species.
4.1b Some organisms reproduce asexually with all the genetic information coming from one parent. Other organisms reproduce sexually with half the genetic information typically contributed by each parent. Cloning is the production of identical genetic copies.
4.1c The processes of meiosis and fertilization are key to sexual reproduction in a wide variety of organisms. The process of meiosis results in the production of eggs and sperm which each contain half of the genetic information. During fertilization, gametes unite to form a zygote, which contains the complete genetic information for the offspring.
