Amanda Sefton (Daytripper) has normal fingers and toes and normal color vision. Her mother is normal in all respects, but her father is color blind (X- linked recessive) and syndactylous (autosomal dominant). Kurt Wagner (Nightcrawler) is color blind and syndictylous. His mother has normal color vision and normal fingers and toes, but he didn't know his father. As their genetic counselor, answer the following questions based on Kurt and Amanda marrying and starting a family. What is the probability of having a child that has syndactyly? (Enter your answer as a decimal; Example = 0.8782)

What is the probability of three having non webbed fingers and one having webbed fingers? а. 1/2 b. 2/3 С. 3/4 d. 1/8 e. 4

A couple comes to you, a genetics counselor, asking for you to explain to them their risk of having a child with cystic fibrosis. Cystic fibrosis is a recessive condition that impacts the lungs and the digestive system. The man, Julian, has a brother with the condition. He was tested for the gene, and he found out that he is a carrier (Ff), and his significant other, Gabby, is also a carrier (Ff). Use this information to answer the quesitons below.   Identify the genotype of Julian. Homozygous recessive   Homozygous dominat   Heterozygous

Please do the pedigree in the attached picture

An autosomal recessive form of deafness is caused by a mutation in the ESPN gene (E = dominant allele and e = recessive allele). An autosomal recessive disease called Usher syndrome is caused by a mutation in the USH2A gene (H = dominant allele and h = recessive allele). The ESPN and USH2A genes are far apart on chromosome 1.   Iris's genotype= eeHH Zacharias' genotype= EEhh   Zacharias and Iris have a daughter named Gianna (EeHh) who produces an eh gamete.    Here are some pictures of metaphase I cells before recombination has been resolved. Which one of the pictures correctly depicts Gianna's metaphase I cell that could divide to produce her eh gamete? (Hint: it is useful to consider the gametes that Iris and Zacharias each contributed to Gianna)

A genetics counselor, Nashaly Montez, notices an odd pattern in Devin’s pedigree, a propensity for cancer development in his family at a higher incidence in males compared to females. This suggests to Nashaly an X-linked recessive disorder that is not manifesting in females as frequently compared to males who only have one X chromosome. She brings this to the attention of Devin’s primary health care provider who has his client checked for common cancer-causing mutations. A mutant LOF Fox3 regulatory allele is found that has an early NONSENSE codon that prevents protein expression. This is unfortunate, since in its wildtype form the protein is normally tumor-suppressing.   1)  If Devin’s mother is a carrier of the mutant LOF Fox3 gene, what is the likelihood he will inherit the defective X responsible for the condition.   a 100% since he only inherits one X from his mother. b 25% due to the typical 3:1 ratio that manifests in recessive disorders. c 0% since he is…

A 20-year-old woman comes to your genetic counselling center because she knows that Huntington disease occurs in members of her family. Huntington is an autosomal dominant disease that often becomes apparent around 35–40 years of age. Her paternal grandfather was afflicted, but so far her 41 year old father shows no symptoms. Her two great-great grandmothers on her father's side were healthy well into their 90s, and one of her great-great grandfathers died of unknown causes at 45. Testing for Huntington disease is extremely expensive, but she is concerned that she may fall victim to this disease and wants to plan her life accordingly. After examining her pedigree you advise her to: not get tested because her father is only a carrier and it is very unlikely her mother is a carrier. not get tested because there is no possibility that she is homozygous. get tested because her father could be a carrier. not get tested because only males in her family get the disease. not get tested…

Based on the information shown (picture) draw the pedigree for this family in the space provided below. Make sure to indicate Lee, the proband, with an arrow and use the proper svmbol for individuals who have died from cancer. Remember to also label each generation with roman numerals.

Mrs. and Mr. Bond have five children, Janine, Jaliyah, Joliette, Jelani and James Jr. Mr. Bond suffers from fragile X syndrome, an X-linked disease (i.e., on chromosome X) which is also dominant. Mrs. Bond is healthy. Janine, Jaliyah, Joliette and Jelani have fragile X syndrome, while James Jr. is healthy. Is there reason to suspect infidelity in this family?
