Subject AreaScience
Grade Level7th
Week #1-22-18 to 3/2/18
Unit of InstructionGenetics
Standard(s) Taught

SC.7.L.16.1
Understand and explain that every organism requires a set of instructions that specifies its traits, that this hereditary information (DNA) contains genes located in the chromosomes of each cell, and that heredity is the passage of these instructions from one generation to another.

SC.7.L.16.3
Compare and contrast the general processes of sexual reproduction requiring meiosis and asexual reproduction requiring mitosis.

SC.7.L.16.2
Determine the probabilities for genotype and phenotype combinations using Punnett Squares and pedigrees.

SC.7.L.16.4
Recognize and explore the impact of biotechnology (cloning, genetic engineering, artificial selection) on the individual, society and the environment.

Advanced Standards
SC.912.L.16.16
Describe the process of meiosis, including independent assortment and crossing over. Explain how reduction division results in the formation of haploid gametes or spores.

Advanced
SC.912.L.16.2
Discuss observed inheritance patterns caused by various modes of inheritance, including dominant, recessive, codominant, sex-linked, polygenic, and multiple alleles.

Learning Targets and Learning Criteria

Students will:
• describe heredity as the passage of traits from one generation to another, for example:
          o inherited vs. acquired, ex: a skin wound would not be passed on to offspring, etc.
• explain why every organism requires a set of instructions to specify its traits
• explain how genes store hereditary information (in DNA) and where genes are located within a cell
• describe the location of genes: cellsnucleus–>chromosomeDNA gene

Students will:
• differentiate between the general processes of sexual reproduction (requiring meiosis) and asexual reproduction (requiring mitosis)
• identify both the advantages and disadvantages of sexual and asexual reproduction
• differentiate between mitosis and meiosis, including:
o a complete set of chromosomes in mitosis vs. a half set of chromosomes in meiosis
(Students do NOT need to memorize the phases of mitosis or meiosis)

Students will:
• differentiate between dominant and recessive traits
• differentiate between genotype and phenotypes
• create and solve Punnett Squares to determine the probabilities for genotype and phenotype outcomes
o Punnett Squares will be given in %
• analyze pedigrees to determine probabilities of genotypes and phenotypes
• explore the benefits and drawbacks of biotechnology, such as:
o cloning, artificial selection, genetic engineering, etc.
o address the impact on individuals, society, and environment

Advanced Standards:
1. describe the process of meiosis, including independent assortment and crossing over
2. explain how reduction division results in the formation of haploid gametes or spores

Advanced:
1. discuss observed inheritance patterns caused by various modes of inheritance, including dominant, recessive, codominant, sex-linked, polygenic, and multiple alleles
