A new genetic disorder called "Blumberg's disease" is found to involve heterozygous alleles, is recessive, and is characterized by incomplete dominance. Discuss the implications of this description concerning the inheritance of this disorder
What will be an ideal response?
Heterozygous alleles occur when the alleles in a pair of chromosomes differ from each other. In this case, the individual will have one non-Blumberg's disease allele and one allele for Blumberg's disease. A recessive allele's instructions are ignored in the presence of a dominant allele. In incomplete dominance, one allele does not dominate another completely. In incomplete dominance, the phenotype that results often falls between the phenotype associated with either allele. Individuals with two recessive alleles (one from each parent) are likely to inherit this disease. Individuals with at least one dominant allele are unlikely to develop the disease.
