Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.

- Forward Genetics Analysis uses a variety of beneficial approaches to identify never before described genes. For each of the following approaches or outcomes, briefly (maximum 2 sentences) discuss in your own words, their purpose in Forward Genetics Analysis. c) Mendelian ratios d) Genetic screenISSR is generally a dominant STS DNA marker. Nonetheless, with validated experimental evidence (e.g. laboratory and population genetics data), the marker can be used in codominance marker genotyping. Briefly explain each case below: a) Codominant marker targets specific locus and reveals allelic variations in that locus among DNA samples. b) Dominant marker: primers can complement other repeat sequences or in multiple loci thereby non-specificity in sampled genomes.A complex biochemical pathway is shown below, along with the alleles that either promote or inhibit each step of the pathway leading to a phenotype. Gene A has alleles A and a, B has alleles B and b, and so forth. Genes B and C are duplicate dominant epistatic lethal as heterozygotes (i.e. Bb Cc are lethal). Genes D and E are duplicate dominant epistatic (i.e. dd eg = desired phenotype). If I were to cross AA Bb cc Dd Ee with aa BB Cc Dd e, (i) (ii) What proportion of all offspring don't show the phenotype? What proportion of offspring survive? Gene A Gene B B Gene D a Gene C Gene E
- 1. a) If you were at risk of a fatal disease such as Huntington’s disease and only the 95% accurate preliminary genetic test was available, would you take the test? After all, 95% of the time the test would tell you whether you would eventually get Huntington’s disease or whether you did not have to worry about getting this disease. b) The linkage distance between the DNA sequence used in the test and the actual Huntington’ disease locus was 5%. In a large sample of the Venezuelan family, what percentage of people would inherit the DNA sequence but not the Huntington’s allele (i.e. be a false positive test for Huntington’s)? What percentage of that large Venezuelan family would not inherit the DNA sequence but would inherit the Huntington’s allele (i.e., be a false negative test for Huntington’s)?As the leading scientist in a biomedical science laboratory, it is up to you to give advice to your lab assistants when they are having problems with their experiments. What advice would you give to your assistants that are having the following problems: After performing a polymerase chain reaction (PCR) and agarose gel electrophoresis to confirm the presence of the CO1 gene of 750bp. a. They observe no band appearing on an agarose gel. What would be your conclusion? b. They observe three bands of different sizes that resemble a smear on the gel. Advise. a. They observe a single band on the gel and conclude that the PCR product is an exact copy of the original template DNA. Would you support their conclusion? ExplainIf you wanted to make a mouse model for any of the following human genetic conditions (a–d), indicate which of thefollowing types of mice (i–vi) would be useful to your studies. If more than one answer applies, state which type ofmouse would most successfully mimic the human disease:(i) transgenic mouse overexpressing a normal mouse protein; (ii) transgenic mouse expressing normal amounts of amutant human protein; (iii) transgenic mouse expressing adominant negative form of a protein; (iv) a knockout mouse;(v) a conditional knockout mouse; and (vi) a knockin mousein which the normal allele is replaced with a mutant allelethat is at least partially functional. In all cases, the transgeneor the gene that is knocked out or knocked in is a form of thegene responsible for the disease in question.a.

AA2 b) Genes A, B and C are on the same chromosome linked in cis (coupling) conformation. A'is 16 cM from B, and B is 22 cM from C. The distance between A and C is 38 cM. The coefficient of coincidence is 0.55 for a trihybrid test cross. How many individuals with the genotype AabbCc do you expect to see among the offspring of the cross if 1000 offspring are obtained? Please show your calculations and round your answer off to the nearest whole number.Describe the main technique for amplifying a segment of DNA (like the one you suspect is involved in Lee’s cancer) from a complex mixture of genomic DNA.

(Hint: This is a technique that is commonly used by laboratories that do genetic testing and various other applications of molecular biology.)Hi, I would like to know which program is used for the graphical presentation of the results of a meta-analysis of genome-wide linkage scans?
- A RFLP is discovered that is linked to the gene for Duchenne’s muscular dystrophy (DMD). DMD is an X-linked, recessive trait. The RFLP is 2 map units from the gene for DMD. Consider the following pedigree and Southern blot using a probe that hybridizes to the RFLP. Which band/s is/are associated with DMD? What is the genotype for individuals 3 and 4? (Remember, this is an X linked disease, so use X’s and Y’s to denote). Individual 9 married a man who does NOT have muscular dystrophy, and she is pregnant. DMD is an X-linked trait. What is the probability for their child to have DMD? An amniocentesis is performed and it is determined that 9’s child in utero has only a 10 kb band that hybridizes to the same probe used above. What can you say about the child now?What are ‘Selectable marker’? What is their use in genetic engineering?What is preimplantation genetic testing? Give an example of a condition screened for? Do you agree with preimplantation screening and what are some of the ethical concerns surrounding the practice?
