7.4 Human Genetics and Pedigrees
• The basic principles of genetics are the same in all sexually reproducing organisms.
– Inheritance of many humantraits is complex
– Single-gene traits areimportant in understandinghuman genetics.

A pedigree is a chart for tracing genes in a family.
Pedigree Key:
• Phenotypes are used to infer genotypes

7.4 Human Genetics and Pedigrees
Jamie and Joe married in 1912. Joe was homozygous dominant for a Widow’s Peak, while Jamie did not have a Widow’s Peak. They had two children: A son named Kyle and a daughter named Marie.
Kyle married a woman who had no Widow’s Peak.Marie never married. Kyle and his wife had three children: Two boys and a girl.
•Do Kyle and Marie have Widow’s Peaks?•What percent of Kyle’s children can we expect to have Widow’s Peaks? •What percent of Kyle’s children can we expect to have NO Widow’s Peaks?
On the top of pg. 86, please create this pedigree and answer the following questions. Always include GENOTYPE when possible:

7.4 Human Genetics and Pedigrees
In pedigrees that show Autosomal Recessive Traits/Disorders only a few organisms, will be shaded in. •Only will show up if heterozygotes mate, may skip a few generations before reappearing.• REMEMBER: if it is an autosomal recessive disorders CARRIERS will be present and must be half shaded in.

7.4 Human Genetics and Pedigrees
Mary and Joe were married in 1950.
Both Mary and Joe were carriers for a fatal recessive disorder called Cystic Fibrosis.
They had three children: A son named Pete who was a carrier, a son named Charles who was not a carrier and did not have the disease, and a girl named Isabel who died from Cystic Fibrosis.
Pete married a woman who was homozygous dominant. Pete and his wife are worried about having a child with Cystic Fibrosis.
Should they worry? What are the chances of any of their children having Cystic Fibrosis? Carriers?

Females can carry sex-linked genetic disorders.
• Males (XY) express all of their sex linked genes.• Expression of the disorder depends on which parent carries
the allele and the sex of the child.
