- Pedigree 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 want to know the results of the cancer, heart disease, and TSD tests if you were Sarah and Adam? Is it their responsibility as potential parents to gather this type of information before they decide to have a child?Pedigree analysis is a fundamental tool for investigating whether or not a trait is following a Mendelian pattern of inheritance.

A simple blood test performed on both Sarah and Adam could determine whether they are carriers of this mutation. If Sarah carries the mutant cancer allele and Adam carries the mutant heart disease allele, what is the chance that they would have a child who is free of both diseases? Are these good odds?Cystic fibrosis is an autosomal disease that mainly affects the white population, and 1 in 20 whites are heterozygotes. Genetic testing can diagnose heterozygotes. Should a genetic screening program for cystic fibrosis be instituted? Should the federal government fund it? Should the program be voluntary or mandatory, and why?
- The text outlines some of the problems Frederick William I encountered in his attempt to breed tall Potsdam Guards. a. Why were the results he obtained so different from those obtained by Mendel with short and tall pea plants? b. Why were most of the children shorter than their tall parents?In a trait that follows Mendelian rules of inheritance, what is the only way an organism can have the recessive phenotype? A. By having the homozygous recessive genotype B. By being heterozygous for that genotype C. It is not possible to get the recessive phenotype in Mendelian genetics D. If one parent is homozygous recessive for that trait, any offspring are guaranteed the recessive phenotype E. By being homozygous dominant for that genotypeA couple who are about to get married learn from studying their family histories that, in both their families, theirunaffected grandparents had siblings with cystic fibrosis(a rare autosomal recessive disease).a. If the couple marries and has a child, what is theprobability that the child will have cystic fibrosis?b. If they have four children, what is the chance that thechildren will have the precise Mendelian ratio of 3:1 fornormal:cystic fibrosis?c. If their first child has cystic fibrosis, what is theprobability that their next three children will be normal?
- Which if the following is not among Mendels principles? a. There are factors that is transmitted from parent to offspring? b. There are only two kinds of traits, dominant and recessive c. Genes resides in the chromosome d. Pair of single traits segregate randomlyGregor Mendel was a critical contributor to our understanding of inheritance today. In his experiments, he tracked seven visual traits of pea plants and ensured that they produced offspring identical to themselves. What are the terms that we used to identify two separate factors? a. genotype; true breeding b. genotype; cross breeding c. phenotype; true breeding d. phenotype; cross breedingColor blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.
- What is Mendelian inheritance? a. Mendelian genes code an entire phenotype so that children will not be clones of their parents. b. Mendelian genetics are those genes that code for dominant or recessive illnesses but only if no polygenic traits cancel them out. c. Mendelian genes sit at one loci with one allele from Mom and one allele from Dad. d. Mendelian genetics is when two or more genes at two or more loci express one traitHow can you relate the two principles of Mendel to Chi-Square Values?2. You cross a pure-breeding red guinea pig with short hair and a pure-breeding white guinea pig with long hair. Allof the offspring are long hair and cream colored.a. What type of inheritance is hair length? Hair color? How do you know?b. What are the genotypes of the parents?c. Determine the genotypes and phenotypes and how many are expected for the F2 generation. (Just leaveyour answers as a list with numbers beside them. No ratios required.)
