identify Mendelian inheritance patterns and pedigree analysis.
The geneticist Gregor Mendel performed hybridization experiments on pea plants. He studied the inheritance of seven different traits in the pea plant that led him to propose the law of inheritance. These are also known as Mendel’s laws of inheritance and include the laws of dominance, segregation, and independent assortment.

- 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.

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?Explain the five modes of inheritance in pedigree analysis.
- Suppose you could send a letter back in time to Gregor Mendel. Tell him about what you know of his own work, as well as other techniques, tools, etc. relating to the Inheritance of Traits that we have explored in class. Try to include the following terms/concepts in your response: Alleles, Chromosomes, Traits & Sex-Linked Traits, Pedigrees, Dihybrid Crosses, Homozygous Dominant, Heterozygous, Homozygous Recessive, Karyotype, Non-Disjunction. asap please typed onlyState Mendel's first law of inheritance and explain with help of suitable example.Draw the following pedigree and identify the mode of inheritance (only identify by shading individuals who express the trait). Please provide the genotype for each individual. Remember if you cannot identify whether an individual is TT or Tt please use the T- annotation: The grandmother expresses the trait and the grandfather does not. The first daughter does not express the trait and marries a man who does not express the trait. The second daughter does not express the trait and marries a man who does not express the trait. The son of the first daughter and her husband expresses the trait. The second son of the first daughter and her husband does not express the trait. The second daughter and her husband have twin daughters that do not express the trait.
