Answer the following questions using the pedigree. 1. ABO phenotype of #1 2. Secretor genotype of #3 3. Lewis phenotype of #3 4. Most probable ABO genotype of #4 5. Substances in saliva of #5 6. Lewis phenotype of #4
Understand the Problem
The question is asking to analyze a pedigree chart and answer specific genetic questions regarding ABO and Lewis phenotypes and genotypes of certain individuals. The solution will involve using Punnett squares and understanding genetic inheritance patterns.
Answer
1. B; 2. SeSe; 3. Le(a-b+); 4. AO; 5. B and H; 6. Le(a-b+)
["ABO phenotype of #1: B","Secretor genotype of #3: SeSe","Lewis phenotype of #3: Le(a-b+)","Most probable ABO genotype of #4: AO","Substances in saliva of #5: B and H","Lewis phenotype of #4: Le(a-b+)"]
Answer for screen readers
["ABO phenotype of #1: B","Secretor genotype of #3: SeSe","Lewis phenotype of #3: Le(a-b+)","Most probable ABO genotype of #4: AO","Substances in saliva of #5: B and H","Lewis phenotype of #4: Le(a-b+)"]
More Information
The Lewis blood group system is linked with the secretor status, impacting the substances present in saliva based on one's ABO blood type.
Tips
Common mistakes include misinterpreting the inheritance of ABO and Lewis antigens, or the secretor gene effects.
