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.

- Rewrite the following sentences after correction. The variation in the length of tandem repeat of microsatellite DNA has serious translational affects as this is due to its coding region. Correct: If one parent has sickle cell anemia and other has carrier genotype than there is 25 % chance that any offspring is carrier. Correct: Sickled WBC block the flow of blood and Calcium as they stick together and caused by frame shift mutation. Correct: The N1303K mutation in the CFTR gene of CF patients is autosomal dominant disorder due to insertion of asparagine at 1303. Correct: If a person RBCs have B surface antigen and it will clump with antigen B such clumping indicates Blood type B. Correct: Indirect ELISA can detect polygenic gene expression. Correct:Question.

Correct:Assignment SummaryIn this assignment, you will think of scientific questions that will help you better understand the role ofDNA and chromosomes in the expression of heritable traits in an organism. You will then conductresearch to answer these questions. Finally, you will compose a typewritten document that states yourquestions and provides your answers.Background InformationDNA in the nucleus of a cell contains the genetic code that dictates the structure and function oforganisms. DNA is compressed into structures called chromosomes. Chromosomes are made ofsegments of DNA called genes. Genes are the basic units of heredity in organisms and are transferredfrom parent to offspring.DNA contains the genetic code, or the set of instructions, in the form of triplet codons, for assemblingamino acids into proteins. All organisms share a similar genetic code based on the same DNA codons.The order of the codons differs, allowing for diversity among organisms.Not all DNA codes for proteins.…
- Genetics in Practice case studies are critical-thinking exercises that allow you to apply your new knowledge of human genetics to real-life problems. Case study Michelle was a 42-year-old woman who had declined counselling and amniocentesis at 16 weeks of pregnancy but was referred for genetic counseling after an abnormal ultrasound at 20 weeks of gestation. After the ultrasound, a number of findings suggested a possible chromosome abnormality in the fetus. The ultrasound showed swelling under the skin at the back of the fetuss neck; shortness of the femur, humerus, and ear length; and underdevelopment of the middle section of the fifth finger. Michelles physician performed an amniocentesis and referred her to the genetics program. Michelle and her husband did not want genetic counseling before receiving the results of the cytogenetic analysis. This was Michelles third pregnancy; she and her husband, Mike, had a 6-year-old daughter and a 3-year-old son. At their next session, the counselor informed the couple that the results revealed trisomy 21, explored their understanding of Down syndrome, and elicited their experiences with people with disabilities. She also reviewed the clinical concerns revealed by the ultrasound and associated anomalies (mild to severe intellectual disability, cardiac defects, and kidney problems). The options available to the couple were outlined. They were provided with a booklet written for parents making choices after the prenatal diagnosis of Down syndrome. After a week of careful deliberation with their family, friends, and clergy, they elected to terminate the pregnancy. Should physicians discourage a 42-year-old woman from having children because of an increased chance of a chromosomal abnormality?Essay: Answer the following questions in paragraph form. Create atlest 3-5 sentences each to support your answer. Base on your own opinion, what does genetics mean? What is its relationship to all living things? What is the connection of Genetics and DNA with each other? Are they related or not? Give your own opinion and you can also cite an example if needed. What is DNA, rDNA and mtDNA? Explain each function. What are the advantages and disadvantages of genetic engineering? If you were given the chance to genetically modify an organism, what would it be and what would you like to modify from that organism?Please help me to answer the following: 1. Explain how the synthesis of a DNA daughter strand growing toward a replication fork differs from the synthesis of a daughter strand growing away from a replication fork. 2. The base sequence ACGTCT represents a portion of a single strand of DNA. Please draw the complete double stranded molecule for this portion of the strand and use the representation to illustrate the replication of the DNA strand.Please clearly identify the nucleotide bases involved, the new strands formed, and the daughter DNA molecules. 3.
