How do you figure out the geno and phenotype from the info given? 2 pages out the lab but I figured once explained I’ll be able to do understand and do the rest!
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.

- Answer the following question from the photo:arrow_forwardSuppose two parents, a father with the genotype AaBbccDd and a mother with the genotype aaBbCcDd, want to have children. Assume the loci are inherited independently of each other. Enter your answers as the most simplified fractions (e.g. 1/8 instead of 2/16). What proportion of the offspring are expected to have: The same genotype as the father? The same phenotype as the father? All dominant phenotypes? All recessive phenotypes?arrow_forwardJust for fun, imagine that “shirt-striping” is a phenotypic character caused by a single gene.

- Can you please not type the answer can you write it on a paperarrow_forwardA student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait)? Both children would inherit the trait. Both children would not inherit the trait. Each child has a 50% chance of inheriting the trait. One child would inherit the trait and one child would not.arrow_forwardConstruct an imaginary pedigree that represents the inheritance pattern of Groats Disease (not a real disorder) Imagine a family tree detailing the inheritance pattern of Groats Disease (not a real disorder), a condition we'll say follows an autosomal recessive pattern. (It must follow an autosomal recessive pattern). • • In this pedigree include 5 generations, 25 individuals, and 5 affected individuals. Proper Pedigree Notation (circles, squares, shading, etc.) Names, ages, and genotypes for all represented individuals (listed beside or under the representative symbol).arrow_forward
- This pedigree (below) shows inheritance of a genetic disorder in a family. Assume the trait is rare. What is the mode of inheritance for this trait? [Select] You know this because that mode of inheritance is characterized by: [Select] individuals who have the allele express it and • An affected male parent passes the allele to [Select] and [Select] of his daughters. • An affected female parent passes the allele to sons and [Select] [Select] of her daughters. 1008 ㅇㅁㅇㄹ O ✓ of his sons of herarrow_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. 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?arrow_forwardPedigree analysis is a fundamental tool for investigating whether or not a trait is following a Mendelian pattern of inheritance.

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?arrow_forward

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_forwardLook at the pedigree below and answer the following questions related to the human genetic trait depicted in this pedigree. 1. Indicate whether the pattern of inheritance associated with this human trait is most likely to be (i) rare X-linked recessive, (ii) sex-influenced, or (iii) sex-limited. You may assume that the gene is fully penetrant. Then, provide a specific reason that justifies your selection of this pattern of inheritance as the correct one, and also explain why each of the other two alternatives are not correct. As part of your answer, include the phenotypic ratio, including the sex of the offspring, that you would expect to find in each of the three possible scenarios.arrow_forwardRed-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___arrow_forward
