Inherited Disorders and Embryo Screening Quiz

What is the inherited disorder polydactyly II caused by?

• Recessive allele

• Mutated allele

• Dominant allele

• Inactive allele

If a person has one copy of the polydactyly allele and one copy of the normal allele, what will be the outcome?

• They will have polydactyly

• They will not have polydactyly

• They will be a carrier of the allele

• They will have a mutated allele

What is the genotype of a man who is heterozygous for the polydactyly allele?

• XX

• PP

• Pp

• pp

What is the phenotype of the offspring if a man who is heterozygous for the polydactyly allele crosses with a woman who is homozygous for the normal allele?

• 25% will have polydactyly and 75% will be unaffected

• All offspring will have polydactyly

• All offspring will be unaffected

• 50% will have polydactyly and 50% will be unaffected

What is one of the issues around embryo screening?

• It is not expensive

• It leads to the creation of a large number of healthy embryos
