Cystic Fibrosis (CF) is an autosomal recessive condition. Therefore, heterozygous (Cc) carriers do not display symptoms. Two parents who are carriers plan to start a family and you are a genetic counselor helping to advise them about their chances of having children affected by CF.
a) Suppose the couple has 4 children, each one year apart. What is the probability that all 4 children will inherit CF?
b) What is the probability that any 3 of their 4 children will not inherit CF, but 1 will be affected?
c) What is the probability that their first child will not inherit CF, but the younger 3 children will inherit CF?

What is the probability that individuals II-1 and II-2 will have a son with NF1? Record your answer as a value between 0 and 1 rounded to two decimal places.arrow_forwardA patient has two parents with Huntington's disease. They may not have inherited this autosomal dominant disorder due to: 1) increased DNA repeats (CAG) during spermatogenesis 2) incomplete penetrance 3) inheriting one recessive allelearrow_forward
- 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.arrow_forwardSuppose a woman who is a carrier of sickle-cell trait (making her a heterozygote) has children with a man who is totally healthy and does not carry the gene for sickle-cell trait at all. Which one of the following is true about their potential children? (Draw a Punnett square on scratch paper if it helps you.) A) None of their children will have sickle-cell disease. B) All of their children will have sickle-cell disease. C) All of the couple's children would be heterozygous carriers like the mother.arrow_forwardPlease answer this question.arrow_forward
- *Cystic fibrosis is a rare autosomal recessive condition. phenotypically normal man whose father had cystic fibrosis marries a phenotypically normal woman from outside the family.² a) Draw the pedigree as far as described. b) If the frequency of heterozygotes in the general population is 1/50, what is the probability that the couple's first child will have cystic fibrosis? c) If the first child does have cystic fibrosis, what is the probability that the second child will be normal?arrow_forwardBelow 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?arrow_forwardEpilepsy is a central nervous system (neurological) disorder in which brain activity becomes abnormal, causing seizures or periods of unusual behavior, sensations and sometimes loss of awareness. For epilepsy, the concordance values are 72% for monozygotic twins and 15% for dizygotic twins. 1) Is this a single gene inheritance or multifactorial disease? 2) Is there a strong genetic or environmental cause to the development of this disease? If both genetic and environmental causes are implicated, you have to indicate each of them separately.arrow_forward

Individuals with normal (wildtype) phenotype have the genotype (F). If two heterozygous individuals marry and have 8 children, what is the probability that: a) four will be normal and four will have cystic fibrosis? b) one will have cystic fibrosis and seven will be normal? c) All eight children will have cystic fibrosis?arrow_forward2) The length of your eyelashes follows an autosomal inheritance pattern.
