Study the data table shown for deafness (autosomal recessive disease) in a family. On a separate piece of paper, develop a deafness pedigree chart for the family. Be
sure to use proper symbols.
Generation I Generation II Generation III
Genotype Gender Genotype Gender Spouse’s
Genotypes

Grandchildren’s
Genotypes/Gender
Dd M DD M Dd DD/M & Dd/F
Dd F Dd F DD Dd/F
dd M Dd dd/F & Dd/M

D = normal hearing, d = deafness
Once you are done, use these guidelines to continue the chart to the next generation:
1. All of the Generation III people marry people who carry the gene for deafness.
2. Each couple in Generation III has 2 children.
3. Four children in Generation IV are deaf.
