Professional Commentary

This modeling activity allows students to discover for themselves what Mendel uncovered in his famous pea experiments. It is an excellent introduction to Mendelian genetics which generates discussion and stimulates interest in Mendel's principles. Students are encouraged to use the same observation and critical thinking skills that Mendel used.


Ohio Science Academic Content Standards (2010)
Science Inquiry and Application
Grade 8
Life Science
Species and Reproduction
3. 
The characteristics of an organism are a result of inherited traits received from parent(s).
High School
Biology
Ohio Science Academic Content Standards (2002)
Life Sciences
Benchmarks (6–8)
B.
Describe the characteristics of an organism in terms of a combination of inherited traits and recognize reproduction as a characteristic of living organisms essential to the continuation of the species.
Benchmarks (9–10)
C.
Explain the genetic mechanisms and molecular basis of inheritance.
Grade Level Indicators (Grade 6)
7.
Recognize that likenesses between parents and offspring (e.g., eye color, flower color) are inherited. Other likenesses, such as table manners are learned.
Grade Level Indicators (Grade 8)
2.
Recognize that in sexual reproduction new combinations of traits are produced which may increase or decrease an organism's chances for survival.
Grade Level Indicators (Grade 10)
6.
Explain that a unit of hereditary information is called a gene, and genes may occur in different forms called alleles (e.g., gene for pea plant height has two alleles, tall and short).
8.
Use the concepts of Mendelian and non-Mendelian genetics (e.g., segregation, independent assortment, dominant and recessive traits, sex-linked traits, jumping genes) to explain inheritance.
Scientific Inquiry
Benchmarks (6–8)
A.
Explain that there are differing sets of procedures for guiding scientific investigations and procedures are determined by the nature of the investigation, safety considerations and appropriate tools.
Benchmarks (9–10)
A.
Participate in and apply the processes of scientific investigation to create models and to design, conduct, evaluate and communicate the results of these investigations.
Grade Level Indicators (Grade 7)
3.
Formulate and identify questions to guide scientific investigations that connect to science concepts and can be answered through scientific investigations.
Grade Level Indicators (Grade 9)
5.
Develop oral and written presentations using clear language, accurate data, appropriate graphs, tables, maps and available technology.
6.
Draw logical conclusions based on scientific knowledge and evidence from investigations.
Grade Level Indicators (Grade 10)
2.
Present scientific findings using clear language, accurate data, appropriate graphs, tables, maps and available technology.
3.
Use mathematical models to predict and analyze natural phenomena.
4.
Draw conclusions from inquiries based on scientific knowledge and principles, the use of logic and evidence (data) from investigations.
