What uses have scientists found for linkage disequilibrium? Linkage disequilibrium allows scientists to offer inexpensive tests for inherited risks for certain diseases. Areas of linkage disequilibrium indicate to scientists which sequence was deleted when a mutation occurred in a gene The level of linkage disequilibrium helps scientists determine how long an allele has been in existence. Linkage disequilibrium can show scientists a gene's location if known genetic markers correlate with a phenotype.

How can you use this piece of information to help you explain to your friends what is the significance of mutations in the emergence of new genetic properties (alleles) that may result (or not) in new phenotypic characteristics? (Recall that not all SNPs affect phenotype.)
You are studying 5 genes: a, b, c, d, and e. In an attempt to map them, you perform a series of two-point crosses with the results listed below. Select the appropriate gene order based on the results of your experiment. a-b = 20 map units; a-c = 16 map units; a-d = 12 map unit; b-d = 8 map units; b-e = 4 map units; c-d = 28 map units; c-e = 40 map units; d-e = 12 map units. Group of answer choices 1)e-b-a-c-d 2)e-b-d-a-c 3)a-c-e-b-d 4)a-b-c-d-e
In a study of a muscle disorder, several affected families exhibited vision problems, muscle weakness, and deafness (M. Zeviani et al. 1990. American Journal of Human Genetics 47:904–914). Analysis of the mtDNA from affected members of these families revealed that large numbers of their mtDNA molecules possessed deletions of varying lengths. Different members of the same family and even different mitochondria from the same person possessed deletions of different sizes, so the underlying defect appeared to be a tendency for the mtDNA of affected persons to have deletions. A pedigree of one of the families studied is shown below. The researchers concluded that this disorder is inherited as an autosomal dominant trait, and they mapped the diseasecausing gene to a position on chromosome 10 in the nucleus. Q. What characteristics of the pedigree rule out inheritance of a trait encoded by a gene in the mtDNA as the cause of this disorder?

Pedigree Analysis Is a Basic Method in Human Genetic: What does OMIM stand for? What kinds of information are in this database?
Blue eye color allele (b) is recessive to the dominant to the black eye color allele (B). When we sequence around the locus of the blue gene from 10 pure breed species and 10 black pure breed species we notice difference in dna sequence. The black eye species have short tandem repeat (STR), which is a short DNA sequence that is repeated 6 times in the species with blue eyes, and 10 times in the species with black eyes. These repeats are only 4 cM apart from the orange gene locus. You design a PC test that distinguishes between the 6 and 10 STRs by electrophoresis. Make pedigree that will let us to identify which alleles of the blue gene was the dominant and or recessive?
You sample DNA from seven bighorn sheep from a population of 2,000 in the Rocky Mountains of Colorado. You sequence 10,000 basepairs from an intron in a diploid coat color locus. You think the SNP mutation rate is somewhere around 10-3 per generation for the whole locus. How many SNPs do you expect to find?
