Heredity Unit Plan
Start Date______________________End Date________________________
Test Date______________________________________________________
Unit Objectives:
1.Summarize the outcomes of Gregor Mendel’s experimental procedures.
2.Differentiate among the laws and principles of inheritance, including dominance,
segregation, and independent assortment.
3.Use the laws of probability to predict genotypic and phenotypic ratios.
4.Use the laws of Punnett squares to predict genotypic and phenotypic ratios.
5.Examine different modes of inheritance, including codominance, crossing over,
incomplete dominance, multiple alleles, and sex-linked traits.
6.Evaluate karyotypes for abnormalities, including monosomy and trisomy.
7.Relate the chromosome theory of heredity to recent findings in genetic research
(i.e. human genome project, chromosome therapy)
8.Analyze historically significant work of prominent geneticists.
Pre-assessments:
A.Pre-test vocab quiz
B.Circle the number that best shows how well you understand each topic BEFORE
starting any new activities. 1=I have a lot of knowledge, could easily explain and
demonstrate understanding; 2= I know something about it, but would need to
refresh/review before giving a full explanation or demonstrating understanding;
3=I know little or nothing about the topic, need to spend some/a lot of time to learn
about the topic to demonstrate understanding.
Essential Questions:
1.How did Gregor Mendel study inheritance of traits and what’s the significance of
his work?
2.How can genotypes and phenotypes be predicted?
3.What are the different modes of inheritance and how do they differ?
4.What kinds of chromosomal defects can be passed on to offspring?
5.What is the chromosome theory and the past and present research supporting it?
