Question

Using the pedigree below, determine whether the alleles B or C have a dominant or recessive relationship, which allele is dominant, and the genotype for individuals I-1, I-2, I-3, I-4, II-4, and II-5. Use B or C for the alleles and X for unknown alleles. 

Note: White squares/circle indicate normal phenotypes. Dark squares/circles indicate the individual has the condition. The B allele is associated with the condition. Label the pedigree chart with genotypes as needed.

Expert Solution
Step 1

Let B be  the allele for the affected condition and C lor the normal condition. Recessive condition is Expressed in only homozygous condition.In a recessive condition the unaffected parents can give rise to the affected children irrespective of the gender.
