A couple has had a child born with neurofibromatosis. They come to your genetic counseling office for help. After taking an extensive family history, you determine that there is no history of this disease on either side of the family. The couple wants to have another child and wants to be advised about the risks of that child having neurofibromatosis. What advice do you give them?
Because Elsa has received a confirmed diagnosis of beta-thalassemia major, which of the following statements is true about her parents? Only her mother carried the gene that caused her blood disorder. Only her father carried the gene that caused her blood disorder. If her parents have another child naturally, there is a 100% chance that the second child will be diagnosed with beta-thalassemia major. If her parents have another child naturally, there is a 25% chance that the second child will be diagnosed with beta-thalassemia major.
Given the information regarding sickle cell anemia, if two carriers were to have children, what would be the genotypes and phenotypes of their children? Would any of the children show symptoms of the disease?
Barbara and John have two daughters (Madison and Kelly), and one son (Mike), all have normal red blood cells. Their other son (Chase) has been diagnosed with sickle cell. Barbara recently gave birth to another son (Barry) who also has been diagnosed with sickle cell. Barbara’s mother (Beth) has sickle cell, but her father (Jason), three sisters (Emma, Lori, and Allison), and two brothers (Emmitt and Will) are all normal. John’s father (Jim), mother (Brenda), and brother (Parker) are all normal, but his sister (Demi) has sickle cell. John’s maternal grandparents (Bill and Lonna) are carriers. Barbara’s paternal grandparents (Kevin and Martha) are all normal. make an pedigree
