What is an X-linked inheritance pattern? Use a specific example to explain the role of the father and
mother in this unique inheritance pattern and note the differential impact on male and female
offspring. What will be an ideal response?
In X linked inheritance patterns, X linked recessive traits are more common in males than females. A
color blind female must have a color blind father and a mother who is either homozygous or
heterozygous for the recessive allele for color blindness. Whereas a color blind male need only have a
mother who is heterozygous for color blindness

When using vectors to produce proteins for gene therapy, what are some of the problems that may occur and how has medical science overcome these problems?
A. cDNA produced by vectors active an immune response, tags are therefore added to help the body identify them as self. B. Proteins injected using vectors get degraded too quickly and therefore protective segments have been added to the proteins. C. Virus vectors used may actually cause disease and therefore medical technicians have removed those segments. D. RNA added via vectors to a human may cause a toxic response and so a buffer is added to the vector.
