INSTRUCTIONAL LESSON PLANS

Teacher: Deskins Subject: Biology 1 Period: 4

Dates: December 5 – 9 Unit: Genetics – Pedigrees and Disorders

SOLs Covered by Objectives:

BIO.6 The student will investigate and understand common mechanisms of inheritance and protein synthesis. Key concepts include

a)  cell growth and division;

b)  gamete formation;

c)  cell specialization;

d)  prediction of inheritance of traits based on the Mendelian laws of heredity;

e)  genetic variation (mutation, recombination, deletions, additions to DNA);

f)  the structure, function, and replication of nucleic acids (DNA and RNA);

Objectives:

1) Students will analyze a simple pedigree.

2) Students will investigate fruit fly genetics and traits of the P, F1 and F2 generations.

3) Students will analyze a karyotype and identify various genetic disorders associated with extra or missing

chromosomes. They will look up information about a particular disorder on the internet and present their

findings to the rest of the class.

Instructional/Assessment Strategies:

M 1) Notes / Guided Practice: Gene Mapping

2) IR 7.3 (go over when finished)

3) Notes / Guided Practice: Pedigrees (7.4)

4) Do Pedigree Worksheet (in small groups) – go over it

T 1) Notes / Guided Practice: Pedigrees w/ Sex-linked

2) More Pedigree Practice – Worksheet #2 (in groups)

3) Short Quiz – Do Pedigree problem from the textbook [p. 208 # 26, 27]

4) Read about Fruit Fly Experiments in Text (p. 197-199)

5) Answer p. 199 - #1-4

W 1) Virtual LAB: Fruit Flies (SmartBoard)

2) Introduce Karyotyping

3) IR 7.4 (go over when finished)

R 1) Review Karyotyping

2) LAB: Karyotyping

3) Start Group Research:

– look in text or on internet (use laptops) for info. on the disorder that your

karyotype displayed in the laboratory (if normal individual, assign a disorder)

– jot down notes and name of site where you found information

– be able to answer questions about disorder:

A) Is it lethal?

B) What are associated symptoms/problems?

C) Does it affect certain populations more than others?

D) How is it inherited (sex-linked, extra/missing chromosome, dominant/recessive)?

E) Is there a treatment / cure?

F 1) Finish Group Research

2) Group Presentations – Genetic Disorders from yesterday’s lab

- all partners in group need to contribute to brief presentation and question/answer session

- may use SmartBoard and come to front of room, may present from seat if more comfortable
