Dr. Joseph is testing whether bloodhounds are able to smell people wearing specially designed, airtight bodysuits. In his experiment, a man wearing such a bodysuit hides in a forest, and a bloodhound tries to trail his scent. Dr. Joseph walks along with the bloodhound and monitors its progress. For the results of the experiment to be useful, which of the following should Dr. Joseph do?
A.
He should make certain that he does not know the location of the man in the bodysuit.

B.
He should make certain that the man in the bodysuit gets lost in the forest.

C.
He should give the bloodhound food and water every 30 minutes.

D.
He should give the man in the bodysuit a compass, so that he can find his way out of the forest.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
