Exam 8: DNA Detective: Complex Patterns of Inheritance and DNA Fingerprinting

When the phenotype of a heterozygote is intermediate between both homozygotes, the pattern of inheritance is ________.

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 of the following is the BEST prediction about the offspring of a hemophiliac male and a nonhemophiliac female who is a carrier for the disease?

When a dominant allele has different effects between heterozygous individuals and homozygous individuals, the phenomenon is called

Describing a person as having hemophilia is to indicate his or her

A family tree that is used to follow human matings that have already occurred is a

There are NO sugars on the surface of any of the red blood cells for which blood type?

The pattern of inheritance for Rh factor is best described as ________.

Females inherit two X chromosomes and males inherit one X chromosome. However, there is not a double dose of X gene products in females because of

A person who is homozygous recessive for both blood type alleles has type ________ blood.

If one person in a population has two different alleles of a particular gene and it's known that other people in the population have yet another different allele of this gene, then this is an example of

A woman with type AB blood and a man with type O blood have a child. Which type of blood could the child have?

Because the bones thought to belong to the Romanov family were highly decayed, scientists determined the gender of each deceased individual by utilizing which type of analysis?

Hemophilia is a genetic disease that has plagued the royal houses of Europe. The disease allele is recessive and X-linked. Queen Victoria was a carrier, and her granddaughter Alexandra married Nicholas II, the last czar of imperial Russia. Alexandra was a carrier for hemophilia; Nicholas was normal. Their son, Alexis, was afflicted with the disease. Alexis and his four sisters were killed in 1917. It's most likely that

A normal individual who is a carrier for an X-linked trait such as hemophilia

In humans, the allele for red-green color blindness is X-linked and recessive (X^r; the dominant allele is called X^R). A man with normal color vision marries a color-blind woman who gives birth to a color-blind daughter. From this, we can tell that

What does a half-shaded circle represent on a pedigree chart?

-A pedigree of the British royal family shows that Queen Victoria was the first in the royal line to have

The polymerase chain reaction (PCR)is used to

When comparing the DNA fingerprints of a parent and child, the parent's DNA fingerprint will have which of the following genetic traits?
