The exomesequence does not show homozygosity for any polymorphisms different from the human RefSeq.a. How could the researcher examine the data alreadygathered to try to find the disease gene, assumingthe sequence is accurate?b. If the attempt described in part (a) was unsuccessful, the researcher might contemplate sequencingthe patient’s whole genome. What are the potentialpitfalls of this strategy?Neanderthal Hair Color The MC1R gene regulates pigmentation in humans (Sections 14.1 and 15.1 revisited), so loss-of-function mutations in this gene affect hair and skin color. A person with two mutated alleles for this gene makes more of the reddish melanin than the brownish melanin, resulting in red hair and pale skin. DNA extracted from two Neanderthal fossils contains a mutated MC1R allele that has not yet been found in humans. To see how the Neanderthal mutation affects the function of the MC1R gene. Carles Lalueza-Fox and her team introduced the allele into cultured monkey cells (FIGURE 26.16). FIGURE 26.16 MC1R activity in monkey cells transgenic for an unmutated MC1R gene, the Neanderthal MC1R allele, or the gene for green fluorescent protein (GFP). GFP is not related to MC1R. 1. How did MCR1 activity in monkey cells with the mutant allele differ from that in cells with the normal allele?

- Why does sickle cell anemia remain more prevalent in Sub-Saharan Africa than in the rest of the world? a. Reduced access to medical facilities presidposes Sub-Saharan Africans to an increased chance od disease. b. The prevalence of malaria in Sub-Saharan Africa provided a selective advantage to individuals who were heterozygous. c. Infection with malaria provides a selective disadvantage to individuals who are heterozygous for the sickle cell allele. d. People of African ancestry are genetically predisposed to carry the sickle cell alleleSteven Frank and Laurence Hurst argued that a cytoplasmically inherited mutation in humans that has severe effects in males but no effect in females will not be eliminated from a population by natural selection because only females pass on mtDNA (S. A. Frank and L. D. Hurst. 1996. Nature 383:224). Using this argument, explain why males with Leber hereditary optic neuropathy are more severely affected than females.In a study of a muscle disorder, several affected families exhibitedvision problems, muscle weakness, and deafness (M. Zeviani et al. 1990.American Journal of Human Genetics 47:904–914). Analysis of themtDNA from affected members of these families revealed that largenumbers of their mtDNA molecules possessed deletions of varyinglengths. Different members of the same family and even differentmitochondria from the same person possessed deletions of differentsizes, so the underlying defect appeared to be a tendency for the mtDNAof affected persons to have deletions. A pedigree of one of the familiesstudied is shown below. The researchers concluded that this disorder isinherited as an autosomal dominant trait, and they mapped the diseasecausinggene to a position on chromosome 10 in the nucleus.a. What characteristics of the pedigree rule out inheritance of a traitencoded by a gene in the mtDNA as the cause of this disorder?b. Explain how a mutation in a nuclear gene might lead to deletions…

Which of the haplotypes has the most connectionsto other haplotypes?c. On what continents is this haplotype found?d. Counting the number of SNPs along the branchesof your network, how many differences are therebetween haplotypes 1 and 12?How will this mutation affect descendants of this puppy? O The mutation will cause a genotypic change in this puppy but its descendants will not inherit this mutation. The mutation will not cause a genotypic change in the puppy and its descendants, but will cause a phenotypic change O The mutation will cause a genotypic and phenotypic change in the puppy, but the descendants are not affected by this mutation. The mutation will cause a genotypic change in the puppy but will not cause a phenotypic change in the puppy and its descendants.
