Exam 8: DNA Detective: Complex Patterns of Inheritance and Dna Profiling

Hemophilia is an X-linked recessive allele causing a blood disorder. What are the chances that a daughter of a normal man and a woman, who is heterozygous for the disease, will have hemophilia?

In DNA fingerprinting, amplified fragments of DNA are separated from one another by which process?

Which alleles are dominant to each other in blood type inheritance?

Which blood type lacks the sugar found on the surface of red blood cells in other blood types?

On a pedigree chart, what symbol would represent a son who is affected by a genetic disorder?

Which offspring will receive a harmful allele for a sex-linked trait from a man who carries the allele?

What pattern of inheritance occurs when a light blue-colored flower results from a cross between a dark blue-colored flower and a white-colored flower?

Hemophilia is an X-linked recessive trait in humans. If phenotypically normal parents have children without hemophilia, what information could be determined by a pedigree analysis?

What is the function of Taq polymerase?

In which group can sex-linked traits be expressed?

What term describes phenotypic features that are coded for by several genes, such as eye color in humans?

A woman with type A blood and a man with type B blood have a baby with type O blood. What are the genotypes of the woman and the man?

Because the bones thought to belong to the Romanov family were highly decayed, what type of analysis was used by scientists to determine the gender of each deceased individual?

Why do different people have different DNA fingerprints?

Hemophiliacs have blood that does not coagulate well, and they often die at a young age. The disease allele is recessive and X-linked. Which genetic possibilities can be predicted for the offspring of a hemophiliac male and a nonhemophiliac female who is a carrier for the disease?

What does each different band on a DNA fingerprint represent?

In addition to autosomes, what is contained in a human sperm cell?

What blood type would a child with the genotype IAi have?

What is the most common blood type in the U.S. population?

What pattern of inheritance occurs in the ABO blood system where there are three distinct alleles in human populations?
