Assume all individuals whose alleles cannot be determined do not carry the allele for the disease are not heterozygous. Introduction to Genomics. Do not fill in this field. Each parent must have at least one recessive, white-eye allele.
Copyright holder you represent if other than yourself. She also carries the recessive allele, meaning that she is heterozygous. Other genetic factors sometimes influence how a disorder is inherited.
