Question

Objectives:
1. Infer the unknown phenotypes of individuals on the basis of the known phenotypes of
their family members.​

Answer 1

To infer an individual's phenotype, one must check and analyze the family pedigree.

How to find phenotype?

• Genes show up in different varieties called alleles and every somatic cell contains two alleles for a single gene.
• By looking into the family tree, we see that particular alleles show up or hide in an individual.  
• A trait that might now show up in the second generation will show up in third generation.
