SCIENCE, TECHNOLOGY, AND SOCIETY Imagine that you are a genetic counselor. What advice or suggestions might you give in the following situations? (a) A couple has come for advice because the woman had a sister who died of Tay-Sachs disease. (b) A young man and woman who are not related are engaged to be married. However, they have learned that the mans parents are first cousins, and they are worried about the possibility of increased risk of genetic defects in their own children. (c) A young womans paternal uncle (her fathers brother) has hemophilia A. Her father is free of the disease, and there has never been a case of hemophilia A in her mothers family. Should she be concerned about the possibility of hemophilia A in her own children? (d) A 20-year-old man is seeking counseling because his father was recently diagnosed with Huntingtons disease. (e) A 45-year-old woman has just been diagnosed with Huntingtons disease. She says she will not tell her college-age sons because of the burden it will place on them. Given that the woman, not her sons, is your client, do you have a duty to inform the sons? Explain your reasoning.
I need some help with this fill-in-the-blank problem. The answer choices are bolded and bracketed. Please see the attached photo to complete. 1. In the D2S441 locus, Sophie's allele [10, 12] is maternal and her allele 10 is paternal from [Sam or Bill only, Sam or Harry only, Bill or Harry only, Sam Bill or Harry (either 3)]. 2. Sophie's allele 13 for D19S433 is [maternal, paternal] and her allele 14 could have come from [Sam and Bill only, Sam and Harry only, Bill and Harry only, Sam Bill or Harry (either 3)]. 3. In the FGA locus, Sophie's allele [21, 22] is maternal and her other allele could have come only from [Sam, Bill, Harry]. 4. Based on all STRs in the 3 panels we studied, it is clear that [Sam, Bill, Harry] is Sophie's father. He has one allele of Sophie's alleles for all STR loci 5. Would these results stand in court as proof paternity: [Yes or No] 6. This type of DNA profiling can also be used to determine maternity. Is there any doubt that Donna is Sophie's biological…
Being able to understand the relationship between DNA, mRNA, tRNA, ribosomes and proteins, is necessary for any researcher interested in gene therapy. Gene therapy is dedicated to correcting genetic defects by replacing mutated genes with wildtype versions. This can include complete removal and introduction of a working copy of the entire gene (using knock-outs and knock-ins) or removal of only the actual mutated nucleotide. Sickle Cell Disease is an example of a recessive disorder based on a single-point mutation: GAG becomes GTG, which encodes a new amino acid. One would only need to replace a single base to correct the disorder making it very attractive to gene therapy researchers. The mutant sickle cell allele is called HbS (for sickled hemoglobin) while the wt allele is HbA. Pretend that Arcel Kasongo, a masters student from Cambridge, is studying for an oral exam on gene therapy, and has an especial interest in the disorder since he comes from the Democratic Republic of Congo…

Please help with the following: How does penetrance differ from expressivity in genetics? A. Penetrance is the percentage of individuals with a specific genotype that exhibit the expected phenotype while expressivity is the degree to which a phenotypic character is expressed. B. Penetrance is the degree of lethality of a specific genotype while expressivity is how frequently that genotype is seen in the population. C. Penetrance is the presence of more than two alleles at a locus within a group of individuals while expressivity is the influence of sex on which alleles express themselves. D. None of the above. E. Penetrance refers to the paternal effects of a gene while expressivity refers to the maternal effects of a gene.

DNA helicase Both A and B Both B and C None 2. True or False. Usually, an animal will drink water twice the amount of feed that it will eat 3. This type of allelic gene interaction results in a heterozygous offspring that is characteristically better than the parents in a particular trait affected by the alleles. a. Heterozygosity b.

Organizations that aim to protect the rights of animals have been battling leisure breeders to stop selective breeding because they view it as a form of abuse or cruelty to animals. Selective breeding or artificial selection is a mechanism that has brought a huge impact on the gene frequency of animals especially domesticated ones like dogs and cats. There are cases when breeding animals such as dogs resulted in diseases and malformation or abnormalities in the resulting offspring. Is s it proper to continue selective breeding? Support your claim and your answer in a bulleted format. this is not a writing assignment
