One of the people on the chart is labeled with the letter A. Which of the following statements correctly describes this person's status in the pedigree?   This person does not have the disease, but this person married someone with the disease, and one of the couple's daughters has the disease as well.   This person does not have the disease, but this person's father and one of this person's sisters do.   This person has the disease and has two daughters with the disease.

Piebaldism is a skin condition that causes an infant to be born with white birthmarks due to a genetic mutation. It is an autosomal dominant trait. A woman with piebaldism married a man without it. They have three daughters, two of whom also have piebaldism. One of their piebald daughters married a man who also has piebaldism and they have two sons with piebaldism, one son without it and one daughter with it. Draw the pedigree for this family and fill in as many of their genotypes as you can.

Given the pedigree below, answer the following questions. Note that filled symbols represent affected individuals. You assume that the allele carrying the disease is rare and therefore individuals marrying into the family are unlikely to have defective alleles. Also, assume complete penetrance. Q2) What are the genotypes of the following individuals listed in the table below? Use the uppercase “A” to represent the dominant allele and lowercase “a” for the recessive allele. Individual Genotype II-7   III-5   IV-1   IV-3   I-2   III-7

Based on the observed inheritance pattern and ratio of phenotypes, what are the genotypes of the affected children? Select an answer and submit it. For keyboard navigation, use the up/down arrow keys to select an answer. a)  If c- = Cystic Fibrosis, the children are c-/c-. b) If c- = Cystic Fibrosis, the children are C/C. c) If c- = Cystic Fibrosis, the children are C/c-. d) If c- = Cystic Fibrosis, the children are C.

Below is a pedigree chart of a certain family with a genetic disorder. Shaded individuals show symptoms of the disease. What is the probability that the individual "III-2" (represented with the question mark) will show symptoms of the disease? Hint: Start by determining if this disease is dominant or recessive. 1-1 I-2 I-3 I-4 II-1 II-2 II-3 II-4 II-5 II-6 III-1 III-2 O 0% O 25% 50% 75% O 100%

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…

Below is a pedigree chart for a family that has a history of Alkaptonuria.   Individuals infected with this condition can have darkened skin, brown urine, and can suffer from joint damage and other complications.  Given this pedigree answer the following questions.   Given the data in the pedigree chart is this genetic condition autosomal dominant or autosomal recessive? What are the genotypes for #1, #2, and #3?  If either of the 4th generation "aa" females were to mate with a homozygous dominant male would any of their offspring illustrate the phenotype?  Why or why not?

Refer to the pedigree below for this question. Individuals who are shaded have an X-inked disorder. Those who are not shaded have the normal phenotype. Let "A" and "a" represent the dominant and recessive alleles, respectively. The disorder represented by the shaded symbol to the normal phenotype. Recessive Dominant A list of possible genotypes is given below. Derermine the appropriate genotype for each individual. Type in the number for the correct answer in the space provided. Do not type arything else in the space.

Sickle cell anemia is a genetic disease that causes red blood cells to form incorrectly, slowing the movement of blood and causing tissue damage. A person can be homozvgous dominant for normal blood cell shape, heterozygous or homozygous for sickle cells. Using this information and the figure below, determine the type of inheritance pattern that the sickle cell disorder follows.

Choose a pattern of inheritance (autosomal recessive, X-linked dominant, etc.) and identify a disorder with that inheritance pattern. Explain how using a pedigree will help a family understand their probability of passing or inheriting the disorder.
