You will write the genotypes of each individual who is labeled with a number in the pedigree. Use 'A' to represent the dominant allele and 'a' to represent the recessive allele. Begin by writing in the genotypes of 5 and 6. WebDifferent alleles of the same gene are distinguished with a number following a hyphen (abc4-1 and abc4-2). When only a single allele is known, the hyphen is not needed. Thus abc3 = abc3-1 if only a single allele is known. The same rules of nomenclature apply to both dominant and recessive mutations.
