24. 23andme is a direct to consumer genotyping company that uses a microarray to genotype peopleon 1 million known SNPS in the genome. A man who was adopted wants to know about his ancestry,and purchases a 23andme kit for himself. He finds that of each autosome pair, exactly one isclassified as 100% Sub-Saharan African, while the other is a mixture of various East Asian andEuropean components. He also finds that his X chromosome is 100% Sub-Saharan African. What canthis man confidently infer about his recent ancestry?a. His mother was of Sub-Saharan African descentb. His father was of Sub-Saharan African descentc. He has no Neanderthal ancestryd. He has no mutations relative to his parentse. 23andme mixed up two samples and he can't infer anything

Genetic analysis of one’s genome can give a lot of information about one’s ancestors. Since,…

Rosalind Franklin and Maurice Wilkins Reiji Okazaki and Tuneko Okazaki Matthew Meselson and Franklin Stahl James Watson and Francis Crick Erwin Chargaff and Arthur Kornberg
The following figure shows a screen shot from the UCSC Genome Browser, focusing on a region of the human genome encoding a gene called MFAP3L. (Note hg38 refers to version 38 of the human genome RefSeq)a. Describe in approximate terms the genomic location of MFAP3L.b. Is the gene transcribed in the direction from the centromere-to-telomere or from the telomere-to-centromere?c. How many alternative splice forms of MFAP3L mRNA are indicated by the data?d. How many different promoters for MFAP3L are suggested by the data?
Calculate the number of Alu elements present in the haploid human genome based on the number of Alu elements present in the clones analysed by the entire class. You will need to know the total length of DNA analysed and the number of Alu elements present. For the entire class, 57 Alu elements are present in 174,204 bp.
Are changes that cause high FST found equally across the genome? What areas of the genome would be most affected? Why
A research team interested in mapping human genes discovered a new restriction length polymorphism (RFLP). The nature of the polymorphism is shown in the figure below. a) They test the RFLP in a family with the pedigree below. The individuals colored blue are affected by hemophilia, a blood-clotting disease. On what chromosome is the RFLP found?
You would like to isolate loci in the genome that influence plant height in tomato plants. Describe how you would achieve this through QTL mapping. Choose a true breeding tall strain and a true breeding short strain and compare the genomic sequences. Choose a true breeding tall strain and true breeding short strain and type them for molecular markers. Mate them together to produce F1 offspring and evaluate whether the F1 are tall or short. Choose two true breeding tall strains and compare the genomic sequences. Choose a true breeding tall strain and true breeding short strain and type them for molecular markers. Mate them together to produce F1 offspring. Genotype the F1 to identify makers that are associated with differences in plant height. Choose a true breeding tall strain and true breeding short strain and type them for molecular markers. Mate them together to produce F1 offspring, then backeross the F1 offspring to produce F2 offspring carrying recombinant chromosomes from tall…
A pair of paralogous repeats, A and B, have 96% sequence similarity and therefore can promote non-allelic homologous recombination (NAHR). They exist in four possible arrangements in a genome, illustrated below as arrangements 1 – 4. What is the result of NAHR between repeats A and B in arrangement 1? A.Translocation between chromosomes 1 and 2 resulting in monocentric chromosomes B.Deletion or duplication of the region between A and B C.Translocation between chromosomes 1 and 2 resulting in acentric and dicentric chromosomes D.Inversion of the region between A and B
At the beginning of the 20th century, scientists argued whether DNA or protein would be the element of "inheritance?" a) Which molecule did they think would carry all the genetic information and why? b) Describe the contribution of Griffith, Avery et al., Hershey & Chase, and Watson and Crick in the field of genetics.
