Chapter 1, Problem 1P
Genetics affects many aspects of our lives. Identify three ways genetics affects your life or the life of a family member or friend. The effects can be regularly encountered or can be one time only or occasional.
Expert Solution & Answer
Summary Introduction
To review:
Three major affects of genetics on our lives or the lives of a family member or friend. Whether these genetic effects are encountered regularly or occur once or occasional.
Introduction:
Genetics is the branch of biology that is concerned with the study of heredity, genes and genetic variation in organisms. Mechanism of trait inheritance and molecular inheritance of genes are considered as the primary principles of genetics in 21st century. The study of gene structure, function, variation and distribution plays a vital role in everyday life of human beings. Genetics in combination with organism’s environment influence the development and behaviour of the organism.
Explanation of Solution
The genetic information present in DNA is organised in a large number of specific coded instructions called as genes. This genetic information, affects our day to day life by a number of ways. The physical appearance of the people such as the eye colour, texture of the hair and many other features depends upon the genetic structure of the organism. Genetics also determine the pattern of some diseases and conditions that run in the families. Thus it can help in understanding the risk of passing the disease on to their children by knowing the family history or pedigree of the disease. Health care professionals uses genetics for the identification of certain conditions in the babies before they born, by using techniques such as prenatal testing. The studies based on human families have indicated that overall variation in adult lifespan (approximately 20-30%) is accounted by genetic factors.
The type of genetic effect will determine whether it will encounter regularly or occur one time or occasionally. For example, the physical appearance of a person is a type of genetic effect that encountered regularly whiles the occurrence of genetic disease seen occasionally.
Conclusion
Thus it is concluded that physical appearance of a person, pattern of some specific diseases and the overall variation in adult lifespan are the three major genetic affects of our lives or the lives of a family member or friend.

- The world can be a scary place. There are many disease causing organisms and genetic disorders that can make life difficult. As you read the chapter, be thinking about your family history of genetic disorders, how these disorders are passed on through generations, and what types of testing can be done to look for these alleles. In this exercise you will reflect on the pros and cons of genetic testing and how it may affect you. Please remember to add a question to engage your classmates in the discussion. What might the consequences be of having this information (e.g. health insurance coverage, privacy, etc.)?arrow_forwardPedigree analysis is a fundamental tool for investigating whether or not a trait is following a Mendelian pattern of inheritance. It can also be used to help identify individuals within a family who may be at risk for the trait. Adam and Sarah, a young couple of Eastern European Jewish ancestry, went to a genetic counselor because they were planning a family and wanted to know what their chances were for having a child with a genetic condition. The genetic counselor took a detailed family history from both of them and discovered several traits in their respective families. Sarahs maternal family history is suggestive of an autosomal dominant pattern of cancer predisposition to breast and ovarian cancer because of the young ages at which her mother and grandmother were diagnosed with their cancers. If a mutant allele that predisposed to breast and ovarian cancer was inherited in Sarahs family, she, her sister, and any of her own future children could be at risk for inheriting this mutation. The counselor told her that genetic testing is available that may help determine if this mutant allele is present in her family members. Adams paternal family history has a very strong pattern of early onset heart disease. An autosomal dominant condition known as familial hypercholesterolemia may be responsible for the large number of deaths from heart disease. As with hereditary breast and ovarian cancer, genetic testing is available to see if Adam carries the mutant allele. Testing will give the couple more information about the chances that their children could inherit this mutation. Adam had a first cousin who died from Tay-Sachs disease (TSD), a fatal autosomal recessive condition most commonly found in people of Eastern European Jewish descent. Because TSD is a recessively inherited disorder, both of his cousins parents must have been heterozygous carriers of the mutant allele. If that is the case, Adams father could be a carrier as well. If Adams father carries the mutant TSD allele, it is possible that Adam inherited this mutation. Because Sarah is also of Eastern European Jewish ancestry, she could also be a carrier of the gene, even though no one in her family has been affected with TSD. If Adam and Sarah are both carriers, each of their children would have a 25% chance of being afflicted with TSD. A simple blood test performed on both Sarah and Adam could determine whether they are carriers of this mutation. Would you decide to have a child if the test results said that you carry the mutation for breast and ovarian cancer? The heart disease mutation? The TSD mutation? The heart disease and the mutant alleles?arrow_forwardPedigree analysis is a fundamental tool for investigating whether or not a trait is following a Mendelian pattern of inheritance.

The disease is known to be 60% penetrant. Complete expressivity occurs in only 40% of people that exhibit the disorder. Incomplete expression occurs only when the person falls asleep, but fails to wake up as the lecture ends. a. Must the percentages of penetrance and expressivity sum to 100%? Explain. b. What percentage of students who are homozygous for the recessive allele will both fall asleep at 8:00 a.m. and still be sleeping when the lecture ends? Show your work.arrow_forward
