Chapter 13, Problem 2TYK
The following pedigree shows the pattern of inheritance of red– green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in red.
What is the chance that a son of the third-generation female indicated by the arrow will be color-blind if the father is a normal man? If the father is color-blind?

The following pedigree shows what type of inheritance?
The pedigree shown below shows the inheritance of cystic fibrosis, a disorder that causes severe damage to the lungs and digestive system. Individual 5 shows no family history of cystic fibrosis and is considered to be homozygous for the normal allele. What is the probability that individual 10 is a carrier for the allele leading to cystic fibrosis?
The following pedigree shows the inheritance of Huntington’s disease, a fatal genetic disorder that causes neurodegeneration. Since signs and symptoms usually do not appear until adulthood, many who are carriers may not realize their risk of passing on the disease-causing allele. The following pedigree represents a family in which some people are affected by Huntington’s disease.
Using just the information on this pedigree, is Huntington’s disease caused by a dominant allele or recessive alleles?
What are the genotypes of the grandparents (I-1 and I-2)?
What are the genotypes of the parents (II-6 and II-7)?
If the parents above have another child, what is the chance that they will be affected by the Hungtington’s disease allele?
What are the genotypes of the unaffected children (III-8, 9, 10)?
What is the chance that the unaffected children above will pass on a Huntington’s disease allele to their children?
What is the genotype of the affected child (III-11)?
What is the chance…

- Does the phenotype indicated by the red circles and squares in this pedigree show an inheritance pattern that is autosomal dominant, autosomal recessive, or X-linked?arrow_forwardUsing the pedigree chart attached: Above is a pedigree for colorblindness. Based on the pedigree, is the disease dominant or recessive and is it sex-linked or autosomal? Why? Furthermore, what is the probability that 18 on this chart is affected but the condition, and what is the probability that 18 is a carrier? Why? Are the probability of being a carrier and an affected individual different? Why?arrow_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

Affected individuals are shaded. what is the probability, that the indicated child (IV.1) will be affected by Lesch-Nyhan syndrome? show solutionarrow_forwardIn a cross between an individual with Huntington disease and an unaffected individual, what are the chances their progeny will have the disease, considering that it is a dominant trait?arrow_forwardFor a recessive condition, two normal heterozygous individuals have children. What is the likelihood of their children being affected by this condition? What is the likelihood of their children being carriers without the condition? What is the likelihood of their asymptomatic children being carriers? Suppose that an individual with the condition has children with a heterozygous individual, what is the likelihood of their children being carriers?arrow_forward

What mode or modes of inheritance are possible for the ringed-hair trait in this family?arrow_forwardAssume that color blindness is a recessive character on the X chromosome. A man and woman with normal vision have the following offspring: a daughter with normal vision who has one colorblind son and one normal son; a daughter with normal vision who has six normal sons; and a color-blind son who has a daughter with normal vision.
