Chapter 14 – Human Heredity
big idea is the same as in chapter 11 (intro to genetics), only now we are applying the concepts to humans
Big Idea #10: Hereditary information is inherited and expressed. (The Laws of inheritance in sexual reproduction are determined by genetics. The gene is the common functional unit of heredity.)
14.1 Human Chromosomes (14.1 Lesson Overview PowerPoint 37 slides)
Identify the types of human chromosomes in a karyotype
Describe the inheritance of human traits
Explain how pedigrees are used to study human traits
review chromosomes: Chromosomes and Inheritance
b) Lab: A Chromosome Study (Biology Corner) – cut out chromosomes & build one of two normal or 4 abnormal karyotypes
Learn what a karyotype is
Prepare a karyotype of a normal human’s chromosomes
Prepare a karyotype of an abnormal human’s chromosomes
Chromosome Gallery (chromosomes, genes, traits & diseases):
DAY 142, 143 & 144 – go over 14.1 SW day 144
– finish kayotype lab questions
Simple & Complex Human Inheritance – may need to finish up karyotype lab
Sex-linked Traits Worksheet (12 problems)
Genetics X-linked Genes Fruit fly (10 problems) – biology corner
Sex Linked Traits (no excuses) – 4 problems
SpongeBob Genetics: “Blood Types & Sex-Linked Traits” (9 problems) – revised 2014
Become familiar with traits that are inherited in humans with simple dominant & recessive alleles
Explain how blood types are an example of incompletely dominant alleles
Define the terms X-linked & Y-linked
Describe how red-green colorblindness & hemophilia are sex-linked traits
Predict blood types of potential offspring from parental types or possible parental types from that of offspring
Do problems to demonstrate how sex linked traits are passed from parents to offspring
Mark coins to represent genes & chromosomes in gamete cells of human males & females
Toss two coins together to simulate the offspring observed if muscular dystrophy is sex linked.
Toss two coins together to simulate the offspring observed if muscular dystrophy is not sex linked.
Determine whether or not muscular dystrophy is sex-linked through the analysis of your data & statements supplied by a hospital
Learn the meanings of all symbols & lines that are used in a pedigree
Calculate the expected genotypes for all individuals shown in the pedigree
14.2 Human Genetic Disorders
Explain how small changes in DNA cause genetic disorders
Summarize the problems caused by nondisjunction
My Human Genetics Disorders (Aneuploidy & Dom/Recessive) Notes & Human Heredity PowerPoint (slides 45-72)
borrowed in part from: www.narragansett.k12.ri.us/NHS/.../mrreis/.../Genetic%20Disorders.ppt
Distinguish between anueploidy in autosomes & sex chromosomes, giving examples of each
Become familiar with a variety of genetics disorders

2hour video: 1. instructions for a human being 2. getting the code out 3. one wrong letter 4. the sequencing race begins 5. ramping up 6. genetic variation 7. who owns the genome 8. the business of science 9. finding the cure is hard 10. complexity in proteins 11. the finish line 12. finding disease gene 13 DNA database 14. a family disease 15. genetic modification 16. contemplating the message
NOVA: Cracking the Code of Life This two-hour special, hosted by ABC "Nightline" correspondent Robert Krulwich, chronicles the fiercely competitive race to capture one of the biggest scientific prizes ever: the complete letter-by-letter sequence of genetic information that defines human life—the human genome. NOVA tells the story of the genome triumph and its profound implications for medicine and human health.
DAY 148: Study Island 5d. Mutations & Genetic Variability – make sure 5b DNA & Genetics is also done!
