This data can be further used by analyzing and providing additional information about the influences of certain characteristics on population genetics.

Genomic DNA is heterogenrous because it shows 2 fragments on 2% agarose gel which come from parents, mom and dad. Moreover, the tandem repeats(n) is within the standard limit (14-41) of heterogenic DNA. So, the sample is heteregenerous.

(b) Not all the bands in a given mother’s or father’s DNA profile will have a

And I test this hypothesis by selecting red and white beans out of a sack at random in order to determine the HbS and HbA surviving allele frequencies

This experiment aimed to investigate the allele frequency of the PTC taster gene (TAS2R38) in a small population, represented by the students in class. The genotype obtained from genomic analysis (via PCR and gel electrophoresis) confirmed that the genotypic result is consistent with the phenotypic result observed at the beginning of the lab.

A quantitative allelic imbalance assay was developed to determine differences in gene expression from individual BRCA1/2 alleles. Allele-specific assays quantify gene expression specific to the allele being tested. For the BRCA1 gene, two individuals homozygous for the BRCA1-c.4308T/T or BRCA1-c.4308C/C polymorphism were tested. Complementary DNA (cDNA) was created from reverse-transcription polymerase chain reaction (RT-PCR) using RNAs extracted from blood lymphocytes. RT-PCR uses reverse transcriptase to form an RNA/cDNA heteroduplex that is then amplified by normal polymerase chain reaction techniques to produce a large quantity of cDNA. Ratios of the cDNA from the two alleles were mixed for use in real-time PCR (qPCR). qPCR uses fluorescent probes that anneal to the cDNA during PCR. These probes contain a reporter and a quencher; the reporter fluoresces when separated from the quencher, allowing a computer to measure the number of cycles needed for the fluorescence to exceed background levels (cycle threshold or CT). Using the ratios of cDNAs and ∆CT, a linear regression was computed to form an allelic expression standard curve that can be used to evaluate allelic imbalance. These same methods were repeated with BRCA2 with two individuals homozygous for the BRCA2-c.3396A/A or BRCA2-c.3396G/G allele.

Stephen Liggett, professor of medicine at the University of Cincinnati College of Medicine, and colleagues carried out tests of the DNA of 121 patients with asthma had found 4 different patterns of DNA in a gene that helps to relax muscles in a person's lungs. Lung function was measured before and after treatment with albuterol, with the individual responses correlated to the sequence of variations found in discrete regions of a person's DNA. Albuterol works by blocking the β2-adrenergic receptor. It aiding the flow of air to the lungs by causing muscles to relax and allows bronchial tubes to dilate. Albuterol worked well in those with 1 pattern, not at all in those with another, and moderately in the other 2 cases. Liggett conclude that identifying the genes that affect the way a person responds to the drug will help physicians tailor prescriptions for each patient. The regions in DNA that the researchers were examining are single nucleotide polymorphisms. Some single nucleotide polymorphisms act like typographic errors, causing abnormalities in the DNA, while others do not seem to matter. In this case, researchers had previously found that the β2-adrenergic receptor

The objective of the project is to determine if I carry the allele at the TAS2R38 locus. In order to find that out, DNA was extracted from cells within the mouth. The DNA sample was quantified, amplified by PCR, ran through gel electrophoresis, purified and sequenced. The results for my DNA was not able to be determined through sequencing. The DNA samples of the class recorded that 62% of the participants were tasters (carries the allele at the TAS2R38 locus) and 38% of the participants were non-tasters (does not carry the allele at the TAS2R38 locus).

The uniformed agouti gene has 11 nucleotide deletion which is a recessive type of the gene, the missing nucleotides are a result of mutation the mutation is then inherited and horse breeder specifically breeds for the agouti

The SNPs information (Protein accession number and SNP ID) of the IDUA gene was retrieved from the NCBI dbSNP (http://www.ncbi.nlm.nih.gov/snp/). Known disease-associated mutations in IDUA gene were retrieved from The Human Gene Mutation Database (http://www.hgmd.cf.ac.uk/ac/index.php).

In our study population, there is a significant association between the T allele of the rs7903146 and T2D. The odds ratio of T allele in the present study was (CI 95%; 0.26 (0.12,0.57), -1.36, p=0.26).

Pairs of alternative traits were expressed in the F2 generation on the ratio of ¾ dominant to ¼ recessive (3:1 segregation ratio referred to as Mendelian ratio)

Moreover, the migration of individuals from one genetically distinct population to another is also an important way for alleles to be added to or subtracted from a local population. Whenever an organism leaves one population and enters another, it subtracts its genetic information from the population it left and adds it to the population it joins. If it contains rare alleles, it may significantly affect the allele frequency of both populations. The extent of migration need not be great. However, as long as alleles are entering
