The figures below depict shared chromosomal regions between 2 full-sibling humans (Figure A) and inbreeding localized to chromosomal regions in a dog (Figure B). Despite these figures being described differently for humans and canines, they are based on the same genetic principle. Identify this principle and describe how this principle is used/reflected in the two figures. 12356910111213141516171819202122XInbreeding by Chromosome BETAWe analyzed the areas of inbreeding across your dog's genome.

Consider the case of a hypothetical genetic disease called WhySciEleven (WSE), an inherited disease that results to the inability to complete production of an amino acid “moduleactivity” that results in brain damage if untreated. WSE is due to a recessive allele. Given one WSE occurrence per 10,000 births. Which term in the Hardy-Weinberg equation corresponds to the frequency of individuals who have no alleles for the disease WSE? a. p b. 2pq c. p2 d. q2
900 bacteria had two recessive alleles out of a total of every 10,000 bacteria. Using the Hardy-Weinberg equation(s), determine the frequency of the recessive and dominant alleles.
Human geneticists have found the Finnish populationto be very useful for studies of a variety of conditions.The population is small; Finns have extensive churchrecords documenting lineages; and few people havemigrated into Finland. The frequency of some recessive disorders is higher in the Finnish population thanelsewhere in the world, and diseases such as PKU andcystic fibrosis that are common elsewhere do not occur in the Finnish population.a. How would a population geneticist explain thesevariations in disease occurrence?b. The Finnish population is also a source ofinformation for the study of quantitative traits. Thegenetic basis of schizophrenia is one question that canbe explored in this population. What advantage(s) anddisadvantage(s) can you imagine for studying complex traits based on the Finnish population structure?

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?
Figure 18-22 shows 10 haplotypes from a population before a selective sweep and another 10 haplotypes many generations later after a selective sweep has occurred for this chromosomal region. There are 11 loci defining each haplotype, including one with a red allele that was the target of selection. In the figure, two loci are designated as A and B. These loci each have two alleles: one black and the other gray. Calculate the linkage disequilibriumparameter (D) between A and B, both before and after the selective sweep. What effect has the selective sweep had on the level of linkage disequilibrium?
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…
1.) Brachydactyly is a genetic condition of dogs where the outside toes on the front feetare abnormally small, resulting in dogs with only two toes on those feet. A recessiveallele (b) codes for brachydactyly. A population geneticist sampling dogs in animalshelters in the northeastern U.S. determined that the frequencies of the BB, Bb, andbb genotypes were 0.64, 0.32, and 0.04, respectively. Calculate the frequency of the b allele. And Calculate the frequency of the B allele.

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…
46. In a hypothetical population, a genetic anthropologist has gone in and determined the following genotypes and genotype frequencies for earlobe attachment. From this data, this scientist wants to determine gene frequencies at this locus for the dominant and recessive alleles. Unattached earlobes (E) are the dominant form of the trait while attached earlobes (e) are the recessive form of the trait. At this particular gene locus, the following genotype distribution was determined: (1) dominant homozygote (EE) = 0. 16 (or 16 percent of the individuals are dominant homozygotes for this trait and have unattached earlobes) (2) heterozygote (Ee = 0.48 (or 48 percent of the individuals in this population is heterozygous at this locus and have unattached earlobes) (3) recessive homozygote (ee) = 0.36 (or 36 percent of the individuals in this population are recessive homozygotes and have attached earlobes)...What is the frequency of the dominant allele? * a. 20% b. 30% c. 35% d. 40% e. 60% f.…
