If the test shows that you have the allele for a genetic disorder, you may be able to reduce your risk of developing that disorder with lifestyle changes. B. If the test shows that you have the allele for a genetic disorder, you will, eventually, show symptoms of that disorder. C. Because we know the functions of all the genes in the human genome, genetic tests can give you complete and accurate information regarding your medical health. D. If the test shows that you do not carry the allele for a particular disorder, there is no chance that you will get that disorder.arrow_forwardWhich of the following is true of genomic imprinting? a.

Why would such animals be useful in medical research? : b. What ethical questions are raised by the creation of such transgenic animals?arrow_forward
- a. It is possible to perform DNA fingerprinting withSNPs instead of SSRs as DNA markers, but ingeneral you would need to examine more SNPmarkers than the 13 SSRs used in the CODIS database to be sure of a match. Explain why.b. DNA fingerprinting has been used to verify pedigrees of valuable animals such as show dogs, racinggreyhounds, and thoroughbred horses. However, thetechnology is much harder to apply in these casesthan it is in forensic applications for humans. In particular, many more DNA markers must be examinedin domesticated animals to establish the identity orclose familial relationship of two DNA samples.Why would you need to look at more polymorphicloci in these animals than you would in humans?arrow_forwardGive typing answer with explanation and conclusion If you want to identify genes linked to autism in a mouse model, which genetic approach or approaches could you use?
