Concept explainers
Consider the following three pedigrees, all involving the same human trait:
(a) Which sets of conditions, if any, can be excluded?
dominant and X-linked
dominant and autosomal
recessive and X-linked
recessive and autosomal
(b) For any set of conditions that you excluded, indicate the singleindividual in generation II (1–9) that was instrumental in your decision to exclude that condition. If none were excluded, answer “none apply."
(c) Given your conclusions in parts (a) and (b), indicate the genotype of individuals II–1, II–6, and 11–9. If more than one possibility applies, list all possibilities. Use the symbols A and a for the genotypes.

- Given the following pedigree: Is the trait autosomal or sex-linked? Is the trait dominant or recessive? Based only on the information given, what is the probability that I-2 is heterozygous? Give the genotypes of individuals II-3, II-4. What is the probability that individual III-1 is purebreeding?arrow_forwardThis pedigree traces the inheritance of a trait in humans. Based on this pedigree, is the allele for this disease dominant or recessive? Is it sex-linked? Explain. What genotypes are most probable for the individuals labeled 4, 7, and 10?arrow_forwardIn the pedigree attached, the shaded symbols represent people affected with a neurological disorder caused by an X-linked recessive allele. The normal allele is D and the recessive allele is d. What are the genotypes of every person in this pedigree? Please explain in as much detail as possible.arrow_forward
- What is the most likely pattern of inheritance for this disorder? (Is it autosomal dominant? Autosomal recessive? X-linked dominant? X-linked recessive? Y-linked? Mitochondrial?) Please include two specific pieces of evidence, present within the pedigree, that indicate that this pattern is most likely, as opposed to any other potential pattern. You may assume that the gene responsible for the trait is fully penetrant.arrow_forwardWhen examining a human pedigree, what features do you look forto distinguish between X-linked recessive inheritance and autosomal recessive inheritance? How would you distinguish X-linkeddominant inheritance from autosomal dominant inheritance in ahuman pedigree?arrow_forwardA 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?arrow_forward
- The accompanying pedigree shows a family in which one child (II-1) has an autosomal recessive condition. On the basis of this fact alone, provide the following information. 1) What is the chance that among the three children in generation II who have the dominant phenotype, one of them is AAAA and two of them are AaAa? (Hint: Consider all possible orders of genotypes.) Express your answer to two decimal places.arrow_forwardFor the pedigree shown here, the disorder is caused by a recessive (g) autosomal allele. Label each of the following individuals with the correct genotypa. Generation I, number 2 b. Generation II, number 1 c. Generation II, number 2 d. Generation III, number 3arrow_forwardFor this pedigree, give the most likely mode of inheritance, assuming that the trait is rare. For the pedigree, what is the probability that III-4 and III-5 will have a boy AND he will be affected?arrow_forward
- What is the approximate percentage chance that individual V.2, shown in the pedigree diagrams above will have inherited the X-linked recessive allele shown to be carried by his great great grandmother?arrow_forwardIs this pedigree dominant or recessive. Which best defines this pedigree Autosomal or sex-linked?arrow_forwardWhich of the following is indicated by roman numerals in a pedigree? a.Presence of the studied trait b.Generation c.Sex d.Marriage status Which of the following disorders in humans has an autosomal dominant inheritance pattern? a.Albinism b.Hemophilia c.Tay-Sachs disease d.Huntington’s disease For an X-linked recessive allele, what proportion of female offspring will be carriers in the cross of an affected father and a noncarrying mother? a.50 percent b.0 percent c.100 percentarrow_forward
