SECTION 7.4 Human Genetics and Pedigrees On Page 24 EQ(s): How can pedigrees be used to analyze human inheritance? 04/10/2015

HUMAN GENETICS FOLLOWS THE PATTERNS SEEN IN OTHER ORGANISMS Fruit flies and pea plants have been used to study the inheritance of many traits, but the inheritance of these traits applies to people too Much of what we know about human genetics has come from the study of genetic disorders 04/10/2015

A PEDIGREE IS A CHART FOR TRACING GENES IN A FAMILY Pedigree  a chart that can help trace the phenotypes and genotypes in a family to determine whether people carry recessive alleles. Shows several types of information: 04/10/2015

On Page 23 in your notebook: Tracing Autosomal Genes:  Description:  When looking at the pedigree:  The trait (homozygous recessive)  shaded in  Is heterozygous  half shaded in  Does not have the trait (homozygous dominant)  not shaded at all. 04/10/2015

EXAMPLE OF AUTOSOMAL GENES 04/10/2015

On Page 23 in your notebook: Tracing Sex-Linked Genes:  Description:  When looking at the pedigree:  more males than females will be affected by the disease  more males  shaded in  more females are carriers  more females  half shaded in 04/10/2015
