1. How might a breeder determine if a certain golden retriever is a carrier of an undesierable trait?

A. prepare a linkage map
B. perform a testcross
C. clone the dog
D. splice the undesirable allele into the dog's genome

2. Bone marrow cells with a defective gene are removed from a donor and grown in a sterile flask. Virus vectors with the corrected gene are integrated into the bone marrow cells. The changed bone marrow cells are returnded to the donor. This is an attempt at

A. palindrone formation
B. DNA fingerprinting
C. gene therapy
D. linkage mapping

3. A small amount of DNA obtained from a mummy or from a human long frozen in glacial ice may be cloned through

A. polymerase chain reaction techniques
B. Gel electrophoresis
C. DNA fingerprinitng
D. gene splicing

1. B
In genetics, a test cross, first introduced by Gregor Mendel, is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply, test crosses determine the genotype of an individual with a dominant phenotype.
2. C
Gene therapy is the insertion of genes into an individual's cells and tissues to treat a disease, such as a hereditary disease in which a deleterious mutant allele is replaced with a functional one
3. A
In molecular biology, the polymerase chain reaction (PCR) is a technique to amplify a single or few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.
